Trick or Trace

Image Trace, global swatches, and two kinds of gradient: one pumpkin poster in two colorways

Halloween poster time. You start with a photograph of a pumpkin and turn it into a bold vector stencil with Image Trace. You clean the stencil, put it on a night sky with a moon and a short title, and turn in a midpoint. Then you light the scene: a Radial gradient and the Screen blend mode give the moon a soft glow, and a Freeform gradient shades the pumpkin so it looks round and moonlit. Finally you export an orange poster, change six swatches, and export the same poster in Ghost Blue.

A good stencil reads from across the room. You are tracing the shape of the pumpkin, not every wrinkle in the photo.

Shortcuts are written Windows / Mac. Example: Ctrl+B / Cmd+B. On a Mac, Option is the key some Windows lists call Alt.

We build together. Follow along step by step. When you finish a step early, wait at the check line or try the bonus at the bottom. Use Illustrator only. Your poster must be original: no movie, game, or brand designs.

Rule of the Day
Trace the shape, not the photo. Judge your trace zoomed out, the way someone sees a poster from across a hallway. Tiny marks on the skin do not matter. The outline and the stem do.

What we build today

The starter photo: one pumpkin with a tall stem on a gray background.

Start: the photo

Steps 2 and 3
Image Trace turns it into one dark shape. You delete the white, trim the floor shadow, and keep the pumpkin and stem.
Example finished poster in the Orange palette: orange pumpkin low on the left, glowing moon upper right, frame, and the title AFTER DARK with a small second line.

Finish: the poster

Steps 4 to 7
A moonlit, shaded pumpkin low on the left, a pale moon with a soft glow, a thin frame, and a title with a small second line. Exported twice: Orange and Ghost Blue.

What your files should look like

These are finished examples made in Illustrator by following this walkthrough. Your pumpkin's edge, your title, and your glow will not match exactly, and that is fine.

The class palette

The Orange ASE file contains all seven named colors: six core colors and one optional Stem color. Load it in Step 1 and make sure the swatches are global. Always apply a color by clicking its named swatch in the Swatches panel. Do not type the hex code on individual objects. That link is what lets one swatch edit recolor the whole poster in Step 7. Step 7 gives you the Ghost Blue values to type in.

Steps

Step 1

Start the poster and load swatches

about 6 min
  1. Unzip TrickOrTrace_StudentFiles.zip. In Illustrator, choose File > New. Make one artboard, Width 1800 px, Height 1200 px, Color Mode RGB. Click Create.
  2. Choose File > Save As. Name the file LastName_TrickOrTrace.ai, format Adobe Illustrator (ai). Click Save, then OK in the options box.
  3. Open Window > Swatches. From the Swatches panel menu, choose Open Swatch Library > Other Library (or Window > Swatch Libraries > Other Library). Open Palette/TrickOrTrace_Orange.ase from the unzipped files.
  4. In the Orange library, add Night, Moon, Pumpkin, Glow, Pumpkin Light, and Pumpkin Shade to your document Swatches panel. You can drag each swatch into the document panel. Stem can stay in the library until you try the optional layers.
  5. Inspect the six document swatches. A global swatch shows a small white triangle in its bottom right corner. If one has no triangle, double-click it, check Global, and click OK.
Check your work: The file is saved as an .ai, and six named swatches each show the white corner triangle.
What you should see: A blank white artboard and six new swatches at the end of the Swatches panel.
If not: To see swatch names, open the Swatches panel menu (four lines, top right) and choose Small List View.
Step 2

Trace the pumpkin, not the photographic detail

about 11 min
  1. Choose File > Place, pick Pumpkin_Class_Pexels_673073.jpg from the Starter folder, and click once on the artboard. The photo is bigger than the artboard and hangs off the edge. That is expected. You scale the pumpkin later. Keep the photo selected.
  2. Open Window > Image Trace. Set Mode to Black and White and check Preview. Wait for the preview to draw.
  3. Look at the preview at the default Threshold (128). At the bottom of the panel, read the Paths count. This is what an untuned trace looks like.
  4. Now tune it. Type Threshold 175. Click the arrow next to Advanced and type Paths 20%, Corners 30%, and Noise 50 px. Wait for the preview to update.
  5. Zoom out until the whole pumpkin fits on screen. Check the outside edge and the spot where the stem meets the body. They should be one connected dark shape on white.
  6. The floor shadow joins the bottom of the pumpkin. That is expected. You trim it in Step 3.
Illustrator Image Trace panel showing Black and White mode, Threshold 175, Paths 20 percent, Corners 30 percent, and Noise 50 pixels.
Image Trace controls in Illustrator 2026 on Mac. Click to enlarge. Your panel may look slightly different on Windows.
Check your work: One dark pumpkin with one stem, a mostly white background, and a Paths count of a handful (the tested setting shows about 3).
What you should see: A solid black pumpkin silhouette with its tall stem, sitting on a black shadow strip.
If not: If the stem breaks away from the body, raise Threshold in steps of 5. If the gray background starts turning black, lower it in steps of 5. Compare at the same zoom each time.
Step 3

Expand and clean the stencil

about 9 min
  1. With the trace selected, click Expand in the Properties panel, or choose Object > Image Trace > Expand. The preview becomes editable paths. Undo if you want to go back and retune.
  2. Ungroup with Ctrl+Shift+G / Cmd+Shift+G.
  3. Click the gray area outside the artboard so nothing is selected. Then press V and click the white part of the trace. Only the white shape should highlight. Press Delete. If the pumpkin highlights too, do not delete: click the gray area and try again.
  4. Press M for the Rectangle tool. Draw a wide rectangle over the shadow strip, with its top edge where you want the pumpkin's flat bottom. Make it wider than the shadow on both sides.
  5. Press V. Shift-click the pumpkin so both the rectangle and pumpkin are selected. Open Window > Pathfinder and click Minus Front (the second button in the top row). The shadow and the bottom sliver of pumpkin disappear. If it cut too much, Undo and draw the rectangle lower.
  6. If a piece of shadow still sticks out to the side, draw a small rectangle over just that piece and use Minus Front again.
  7. Delete any small stray pieces. If the stem and body are separate shapes, select only those two and click Unite (the first Pathfinder button).
  8. Select the pumpkin and click the Pumpkin swatch. Save with Ctrl+S / Cmd+S.
Check your work: One orange pumpkin shape with a flat bottom. No white rectangle, no shadow, no strays. Clicking the pumpkin selects the whole thing.
What you should see: An orange pumpkin silhouette with its stem, sitting on the white artboard, with a clean, straight bottom edge.
If not: If you deleted the pumpkin, Undo. If you cannot select the white shape, Ungroup once more and try again. If Minus Front did nothing, check that both shapes were selected and the rectangle was on top.
Step 4

Build the poster

about 9 min
  1. Press M and draw a rectangle that goes past all four edges of the artboard. Click the Night swatch for the fill and set the stroke to None. Choose Object > Arrange > Send to Back.
  2. With the rectangle still selected, lock it: Ctrl+2 / Cmd+2. Now you cannot grab it by accident.
  3. Frame. Press M, click once on the artboard, and type Width 1704 px, Height 1104 px. Click OK. Set the fill to None, click the Stroke square, click the Moon swatch, and set the stroke weight to 3 pt. In the Align section of the Properties panel, click Horizontal Align Center and Vertical Align Center. With one object selected, Illustrator centers it on the artboard, so the frame sits 48 px inside every edge. If it does not move, open the Align menu in that section and choose Align to Artboard, then click the two buttons again.
  4. Press V and click the pumpkin. Hold Shift and drag a corner handle to scale it. Place it low on the left, big enough to feel heavy, with its flat base just above the bottom of the frame.
  5. Press L for the Ellipse tool. Click once in the upper right of the artboard and type Width 320 px, Height 320 px. Click OK. Click the Moon swatch for the fill and set the stroke to None. Leave clear space between the moon and the pumpkin.
  6. Press T, click in an open area, and type a short original title, such as AFTER DARK. Press V, then click the Moon swatch. Pick a plain, bold font and make it big enough to read zoomed out.
  7. Add a small second line under the title. Press T, click below the title, and type a short all-caps line, such as ONE NIGHT ONLY / OCTOBER 30. Apply the Moon swatch and set the size to about 28 pt. Open Window > Type > Character and set Tracking to 200. Line up its left edge with the title's left edge. Keep both lines plain: no effects.
  8. Save with Ctrl+S / Cmd+S.
Check your work: A Night background with no white showing at any edge, a thin Moon-colored frame inside the edges, an orange pumpkin low on the left, a pale moon upper right, and a title with a small, widely spaced second line under it.
What you should see: Three clear levels: a dark sky, a bright pumpkin, and a pale moon and title. The frame and the small second line make it read as a finished poster, not a drawing.
If not: If the background covers everything, it is locked in front. Unlock all with Ctrl+Alt+2 / Cmd+Option+2, choose Object > Arrange > Send to Back, and lock it again.
Step 5

Midpoint turn-in

about 3 minturn-in
  1. Save with Ctrl+S / Cmd+S.
  2. Choose File > Export > Export As. Name the file LastName_TrickOrTrace_Midpoint.jpg. Set the format to JPEG, check Use Artboards, and leave Suffix unchecked if your dialog shows it. Click Export.
  3. In the JPEG Options box, set Quality near the high end, Color Model to RGB, and Resolution to Screen (72 ppi). Click OK. Do not choose High (300 ppi): your file would come out four times too big.
  4. Open the JPEG and look at the whole image. Then upload LastName_TrickOrTrace_Midpoint.jpg to Canvas as your midpoint.
Illustrator Export As options: JPEG format, Use Artboards checked, and Suffix unchecked.
Export As controls in Illustrator 2026 on Mac. Your student file should have one artboard. Click to enlarge.
Check your work: Your JPEG is 1800 by 1200 px and shows the pumpkin stencil, Night background, frame, moon, and both lines of type. No photo, no white, no shadow, no strays.
What you should see: A dark poster with an orange pumpkin and a flat pale moon. The moon has no glow and the pumpkin is still one flat color. Both get lit in Step 6.
If not: If the file name ends in -01, rename it to match before you upload. If art is cut off, export again with Use Artboards checked.
Step 6

Light the scene: Radial glow and Freeform pumpkin

about 10 min

Two gradients, two jobs. A Radial gradient makes even light that spreads from a center, which is what a glowing moon does. A Freeform gradient lets you place colors anywhere on an irregular shape, which is what moonlight on a pumpkin does.

Part A: Radial glow on the moon

  1. Press V and click only the moon. Copy with Ctrl+C / Cmd+C, then choose Edit > Paste in Back, Ctrl+B / Cmd+B. A copy lands right behind the moon, already selected. This copy is the halo.
  2. Choose Object > Transform > Scale. Select Uniform, type 200%, and click OK. The halo grows from its own center to twice the moon's size and stays lined up behind it.
  3. Open Window > Gradient. With the halo selected, click the Radial Gradient button (the second gradient type). The halo fills with a white-to-black gradient.
  4. Under the gradient slider, double-click the left color stop. In the popup, click the Swatches button and choose Glow. Double-click the right stop, choose Glow too, then set that stop's Opacity to 0%. The glow now fades out before the edge.
  5. Open Window > Transparency. With only the halo selected, change the blend mode from Normal to Screen. Click the moon and check that it is still on Normal.

Part B: Freeform shading on the pumpkin

First, know the panel. With a Freeform gradient selected, the Gradient panel shows these controls:

Gradient panel set to Freeform: Type buttons, Draw Points or Lines, Stop with a trash can, Method menu, a color button, Opacity, and Spread.
The Gradient panel with Freeform selected, Illustrator 2026 on Mac. Opacity and Spread stay gray until you select a point.
ControlWhat it doesToday
TypeLinear, Radial, or Freeform. The third button is Freeform.Freeform

OpacityHow see-through the selected point's color is.100% on every pumpkin point
SpreadHow far the selected point's color reaches before it starts blending. Higher spreads the color wider.Values in the table below
  1. Press V and click the pumpkin. In the Gradient panel, click the Freeform Type button and make sure Draw is set to Points. Illustrator adds a few points on its own. Each point is a small circle on the pumpkin.
  2. Clear the automatic points. Click a point to select it, then click the trash can next to Stop (or press Delete). Repeat until one point is left. You will reuse it as point 2.
  3. Build the four points in the table below. Match the picture.
    • To add a point: click an empty spot inside the pumpkin.
    • To color a point: select it, click the color button in the Gradient panel (or double-click the point), and pick the swatch from the Swatches list. Always pick the named swatch, so it recolors in Step 7.
    • To move a point: drag it.
    • To set Opacity and Spread: select the point and type the values in the panel.
    PointWhereSwatchOpacitySpread
    1Upper right of the body, the side facing the moonPumpkin Light100%40%
    2Middle of the bodyPumpkin100%60%
    3Lower left, near the edgePumpkin Shade100%30%
    4Bottom edge, a little right of centerPumpkin Shade100%30%
    Pumpkin with four numbered points: 1 Pumpkin Light upper right, 2 Pumpkin in the middle, 3 Pumpkin Shade lower left, 4 Pumpkin Shade at the bottom.
    Where the four points go. Drawn by a script as a guide; your blend will look slightly different.
  4. Zoom out and judge it. The Spread values are a starting point. If the light patch is too small, raise point 1's Spread. If the bottom is too dark, lower the Shade points' Spread or move them toward the edge. The stem picks up the nearest colors. That is fine.
  5. Save with Ctrl+S / Cmd+S.
Check your work: A soft glow around the moon with no hard circle edge, and only the halo on Screen. The pumpkin is lighter on the side facing the moon and darker at the lower left and bottom.
What you should see: The moon looks lit, and the pumpkin looks round, with moonlight falling on one side of it.
If not: If the halo has a hard edge, check that the right stop is at 0% Opacity. If the pumpkin looks blotchy, you probably have extra points: count them, keep four, and delete the rest. If it is still one flat color, its points all use the same swatch: select each one and pick the swatch from the table.
Optional before the final exports: stem and rib lines about 6 min

Only if you finished Step 6 early. If you are on pace, go straight to Step 7.

What you are making: six thin rib lines and a green stem, drawn on top of your shaded pumpkin. The shading stays visible underneath. The picture shows the four moves.

Four panels: one tall ellipse clipped to the pumpkin, a 55 percent copy, a third copy from Ctrl or Cmd D, then a green stem rectangle drawn last that hides the ellipse tops in the stem.
1: one tall ellipse. 2: a narrower copy. 3: one more copy. 4: the stem rectangle, drawn last, hides the ellipse tops in the stem. Drawn by a script as a guide.

Two habits for this whole section:

Part 1: Set up

  1. Add the Stem swatch #7FA046 from the Orange library to your document Swatches panel. Check that it shows the white Global triangle.
  2. Make a copy of the pumpkin to draw into. Press V and click the pumpkin. Copy with Ctrl+C / Cmd+C, then choose Edit > Paste in Front, Ctrl+F / Cmd+F. The copy lands exactly on top and stays selected.
  3. Turn on Draw Inside. With the copy still selected, press Shift+D until dashed corner brackets appear around the pumpkin. (The mode buttons are the three small circles near the bottom of the Toolbar; Draw Inside is the third.) From now on, anything you draw is trimmed to the pumpkin's outline.

Why a copy? Draw Inside removes the fill from the shape you draw into. Using a copy means the copy goes blank, and your shaded pumpkin underneath still shows.

Part 2: Ribs

  1. Draw one tall ellipse. Press L. Point at the middle of the pumpkin body (straight below the stem, halfway down). Hold Alt (Windows) or Option (Mac) and drag outward. Stop when the ellipse is:
    • a little narrower than the body, with its sides just inside the left and right edges, and
    • taller than the body, with its top above the body and its bottom below the base.
    Only the two curved sides show. They are your first two ribs.
  2. Fix its colors right away. A new ellipse starts with a white fill that hides your shading. With the ellipse still selected, in the Swatches panel:
    • Fill square, then None
    • Stroke square, then Pumpkin Shade
    • Stroke weight 3 pt (in the Properties panel)
  3. Make a narrower copy. Choose Object > Transform > Scale. It may still show Uniform 200% from the halo. Set:
    • Non-Uniform
    • Horizontal 55%
    • Vertical 100%
    Click Copy, not OK. A narrower ellipse appears with the same center and height.
  4. Make one more. Press Ctrl+D / Cmd+D once. That repeats the last scale and copy. You now have three ellipses and six rib lines. Stop there.

Part 3: Stem

  1. Draw the stem rectangle last. Press M. Drag a rectangle that covers the whole stem with room to spare: start above and left of the stem tip, end past the stem's right side, and put the bottom edge where the stem meets the body. Any part of the stem the rectangle misses stays orange.
  2. Color it. In the Swatches panel: Fill square, then Stem. Stroke square, then None. Because it was drawn last, it sits on top and hides the ellipse tops inside the stem.

Part 4: Finish

  1. Turn Draw Inside off. Press Shift+D until the first circle button (Draw Normal) is highlighted. If you skip this, the next thing you draw gets trimmed into the pumpkin.
  2. Press V, click empty space, and zoom out. Save with Ctrl+S / Cmd+S.
Check your work: Six thin rib lines curve down the pumpkin, the stem is green from tip to base, and the Freeform shading still shows everywhere.
What you should see: The same lit pumpkin, now with ribs and a green stem. A thin green line along the top of the body next to the stem is normal; it reads as the base of the stem.
If not: If the pumpkin turned white, gray, or muddy, an ellipse has a fill: press A, click each rib line, and set its fill to None. If a curve shows inside the stem, the stem rectangle is not on top: select it and choose Object > Arrange > Bring to Front. If part of the stem is still orange, select the rectangle and drag its edge to cover the rest. If the lines look too heavy, select them and set the stroke to 2 pt.

For Ghost Blue in Step 7: also change Stem to #A8C6B0. The ribs use Pumpkin Shade, so they recolor on their own. Check both JPEGs.

Step 7

Export Orange, recolor, export Ghost Blue

about 10 minturn-in
  1. Before you change any swatch, export LastName_TrickOrTrace_Orange.jpg with File > Export > Export As, JPEG, Use Artboards checked, and the same JPEG Options as the midpoint.
  2. Use the palette table above to read the new values. Edit the existing document swatches so all linked objects update. In the Swatches panel, double-click Night, type 29435C, and click OK. The background changes without selecting it. Do the same for Moon F4F5FF, Pumpkin 7FB2E5, Glow A9C9FF, Pumpkin Light DDEFFC, and Pumpkin Shade 4F7FB5. If you added the optional stem, also change Stem to A8C6B0.
  3. Check both gradients. If the glow or any part of the pumpkin still looks orange or yellow, select that shape and press G for the Gradient tool to show its stops or points. Double-click the one that did not change and pick the matching Ghost Blue swatch. Check that the halo is still on Screen.
  4. Export LastName_TrickOrTrace_GhostBlue.jpg the same way. Save the .ai file.
  5. Open both JPEGs. Check the whole artboard, the color difference, the title, and the glow. Upload both to Canvas.
Check your work: Two JPEGs with the same layout and different colors, both with a visible glow and a shaded pumpkin. Your .ai file is saved.
What you should see: A warm orange poster and a cold, ghostly blue version of the exact same design.
If not: If one object stayed orange, it was colored by hex code, not by the swatch. Select it, click the right swatch, and export Ghost Blue again with the same name.
Step 8

Bonus: bat Scatter brush

about 8 minbonus

Only after both final JPEGs are uploaded.

  1. Choose File > Place and place Bat_Fallback.svg from the Bonus folder in the gray area off the artboard. Or draw your own one-piece bat silhouette.
  2. Open Window > Brushes. Select the bat, click the New Brush button (the plus sign), choose Scatter Brush, and click OK twice.
  3. Press B for the Paintbrush. Paint a short curved path that crosses the moon. Make sure the new brush is the one selected in the Brushes panel.
  4. Double-click the path's brush in the Brushes panel to open its options. Raise Spacing until the bats are separate. Try Size and Rotation if you like. Click OK and choose Apply to Strokes.
  5. The bats are the Night color, so they show where they cross the moon and glow. That is the look. The source bat can stay off the artboard.
  6. Export both final JPEGs again with the same names and upload them again.
Check your work: A short line of separate bats in silhouette against the moon, in both final JPEGs.
What you should see: Small dark bats flying across the glowing moon.
If not: If the bats overlap into one blob, raise Spacing. If you cannot see them, paint the path across the moon, not across the sky.

My ribs make the pumpkin look gray or muddy.The ellipses have a fill. Press A, click each rib line, and set its fill to None.
A curved line shows inside the stem.That is the top of a rib ellipse. Draw the Stem rectangle after the ribs so it covers them, or select the rectangle and choose Object > Arrange > Bring to Front.
My ribs are uneven or not centered.Delete all but the first ellipse, then use Object > Transform > Scale with Non-Uniform 55% and Copy, so every rib shares the same center and height.
The pumpkin looks blotchy or striped.Delete extra Freeform points, lower their Spread, or move them farther apart.
The moon looks washed out.Set the moon back to Normal in the Transparency panel. Only the halo uses Screen.
One object did not recolor.Select it and click its named swatch. For a gradient, press G, double-click the stop or point that did not change, and pick the Ghost Blue swatch.
My JPEG is huge or tiny.Export again with Resolution set to Screen (72 ppi). The file should be 1800 by 1200 px.
My file name ends in -01.Rename the JPEG to match the turn-in name before you upload.
The JPEG cuts off art.Export again with Use Artboards checked.
I cannot find a tool.Tools hide in groups. Click and hold a tool that has a small triangle in its corner.

What this project was actually about

Image Trace gives you a starting shape, not a finished one. Expanding and cleaning it is the real work: deleting what you do not need and cutting a messy edge into a clean one with Pathfinder. Global swatches turn a palette into a system, so one edit travels through the whole design. A Radial gradient makes even light from a center, and a Freeform gradient shapes light across an irregular object. Screen lets light interact with what is underneath it. You use blend modes again when you put artwork on mockups in Session 6.
