How to Color Sketches in Procreate
StyleFrame Team8 min read
To color a sketch in Procreate, put your line art on its own layer and mark it as a Reference layer. Then create a layer underneath and drag colors in with ColorDrop to block in flat shapes. For painted looks, add new layers set to Multiply (or clipped to your base colors) for shadows, highlights, and blending. Keeping each color area on its own layer makes the file easy to recolor and to hand off to After Effects, Photoshop, or any other pipeline later.
Prepare the sketch before you add color
Clean prep saves more time than any brush choice. Do three things first.
Set up the canvas. Pick a size you can live with for the final output. If the art is headed into a video timeline, work at or above your delivery resolution (3840×2160 for UHD, for example) so you can push in on the artwork later. Higher pixel counts reduce how many layers Procreate lets you have, so balance size against layer count.
Import or isolate the sketch. If you drew in Procreate, copy the sketch layer into your new canvas from the layer menu. If you drew on paper, use Add > Take a Photo or Insert a Photo, scale with the Uniform transform setting, and light the page evenly so the shadows are minimal.
Clean up a photographed sketch. Reduce the saturation to zero with Hue, Saturation, Brightness. Then open Curves and drag the white point inward until the paper turns white and the pencil lines stay dark. Remove leftover smudges at the edges with a soft eraser.
Finally, decide how your line art should look. Black lines are fine, but many illustrators recolor the line layer to a warm brown or deep red so it doesn't feel harsh against the colors. You can do this by locking the layer with Alpha Lock and filling it with a new color, or by shifting the channels in Curves.
Method 1: flat color with Reference layer and ColorDrop
This is the fastest route for cartoons, comics, graphic shapes, and any art that will be animated in cutout style.
- Close your shapes. ColorDrop fills up to the nearest line, so any gap lets color leak across the drawing. Zoom in and patch open corners with a hard brush on the line layer.
- Turn on Reference. Tap the line art layer, choose Reference, and Procreate will treat those lines as boundaries for fills on other layers.
- Make a color layer underneath. Create a new layer below the lines. Select it, then drag a swatch from the color circle into an enclosed area and release.
- Adjust the threshold. After dropping, keep your pen held down and slide left or right. This changes how aggressively the fill reaches into the line edges. Raise it to remove the pale halo between color and line; lower it if the fill spills.
- Use one layer per material. Skin, hair, clothing, and background can each get their own layer. It's more layers, but changes become trivial.
If a fill leaves a thin gap next to the line, don't fight it with an eraser. Raise the threshold, or paint a slightly larger shape on the color layer, since the lines sit on top and will hide any overlap.
Method 2: paint directly on a Multiply layer
For a looser, hand-painted look, skip fills and paint on a layer set to the Multiply blend mode.
- Lock the line art layer (swipe left on it and choose Lock) so you can't paint on it by accident.
- Add a new layer above the lines. Tap the "N" to open blend modes and choose Multiply.
- Paint with a textured brush. Because Multiply darkens whatever is underneath, the black lines remain visible through your color.
- Keep the pressure and opacity low so overlapping strokes build up rather than flatten.
The tradeoff is that painted layers are harder to change later, since every stroke is baked into the pixels. If you expect revisions, paint each major area on a separate layer, or use Method 1 for the base and Method 2 only for rendering.
Block in big shapes first
Whichever method you use, start with the largest areas and work toward the small ones.
- Background first. A flat background color shows you how the other colors will read against it, and it lets you see any gaps in your fills quickly.
- Large shapes, then medium, then small. Skin, clothing, and props go first. Eyes, jewelry, and small details come last.
- Palettes are optional. If you need help choosing, sample colors from a photo or a reference image. In the Color panel, open Palettes, tap +, and create a palette from a photo or file. This gives you a harmonious set without guesswork.
- Keep values in mind. Check your drawing in grayscale occasionally. If two shapes merge into the same gray, they'll compete for attention in motion too.
Add shading and highlights
Once the base colors are down, build form with clipped layers.
Use clipping masks. Create a new layer above a base color layer and choose Clipping Mask. Anything you paint will stay inside the shapes below it, so there's no need to mask or erase around edges.
Shade with Multiply. On a clipped layer set to Multiply, use a desaturated warm or cool color (a reddish purple works well on skin) and paint where the light doesn't reach. Think in planes: surfaces facing away from the light source get darker.
Highlight with Add or Overlay. A second clipped layer set to Add (Linear Dodge) or Overlay can lift highlights and rim light. Use these sparingly; they can blow out quickly.
Try a gray-first pass. Another approach is to shade the drawing in grays on a Multiply layer, then place a color layer beneath both the shading and the line art. The colors mix with the shadows underneath and you get depth with very little effort. This works nicely for portraits and for characters you plan to relight.
Blend and soften
Procreate's Smudge tool, set to a textured brush such as one of the default Painting brushes, will smooth transitions between values. Reduce the brush size and opacity as you work toward the edges. For a softer look, use an airbrush at low opacity on a clipped layer instead of smudging.
Avoid over-blending. Leaving some visible stroke texture keeps the piece from feeling digital and flat, and it gives the art more character when it moves.
Recolor without repainting
Because your colors live on separate layers, you can change them non-destructively:
- Hue, Saturation, Brightness on a single layer shifts one element, such as a jacket, without touching anything else.
- Color Balance pushes shadows, midtones, or highlights toward a different hue.
- Gradient Map can unify the whole illustration under a limited palette.
- Curves tunes the overall contrast and adds a tint to the line art.
Duplicate a layer before experimenting so you can compare versions or revert.
Troubleshooting common problems
- Color covers the lines. The color layer is above the line art without Multiply. Move it underneath, or set it to Multiply.
- Fill leaks across the drawing. There is a gap in the lines. Close it, or lower the ColorDrop threshold.
- White fringe around fills. Increase the threshold, or paint slightly under the line edges.
- Colors look muddy. Too many Multiply layers stacked on each other. Merge or reduce them, and use lighter, more saturated shadow colors.
- Photographed lines look gray. Redo the Curves adjustment and clean the paper tone before coloring.
Bring colored sketches into a motion workflow
Many motion designers use Procreate for concept frames, storyboards, and styleframes, then move into After Effects, Cinema 4D, Blender, or Nuke for production. A few habits make that handoff smoother:
- Name and group layers by function (line, base, shadow, highlight, background) so they remain readable in a PSD.
- Export a layered PSD for compositing in After Effects, plus flattened PNGs for reference.
- Keep transparency clean. Leave the background on its own layer so characters and props can be pulled out easily.
- Work at delivery resolution to avoid soft edges when you scale in a comp.
This is also where can sit alongside Procreate. It's an AI video and motion tool built around artistic control rather than one-click generation. Once your colored sketches are ready, you can use them as references for AI-assisted motion work, so your Procreate artwork stays the source of truth and your compositing pipeline stays where it is.
A quick coloring workflow to follow
- Create the canvas at a size that suits your final output.
- Import and clean the sketch; recolor the lines if you like.
- Mark the line art as a Reference layer and close any gaps.
- Fill the background, then the large shapes, using ColorDrop on separate layers.
- Clip shadow layers (Multiply) and highlight layers (Add or Overlay) to each base.
- Blend selectively with the Smudge tool or a soft airbrush.
- Adjust color with Hue, Saturation, Brightness, Color Balance, or Gradient Map.
- Organize layers and export a PSD and PNGs for your next stage.
Once you have this routine, coloring a sketch becomes a repeatable process rather than a gamble, and your files stay flexible enough for revisions, animation, and compositing.
