How to Automatically Fill Color in Procreate
StyleFrame Team7 min read
The fastest way to automatically fill color in Procreate is ColorDrop: drag the active color from the top-right corner onto a closed shape, hold, and slide left or right to set the Threshold before you lift. For repeated fills, tap Continue Filling to keep tapping areas with the same color. Selections → Color Fill fills an area the moment you finish selecting it, and Fill Layer covers a whole layer in one step.
This guide covers each method, when it works best, and how to stop fills from leaking or leaving fringes. It also covers how to move flat-colored artwork into an After Effects or Nuke pipeline.
Method 1: ColorDrop and Continue Filling
ColorDrop works like a paint bucket you drag into place.
- Pick your color in the top-right Colors icon.
- Drag that color swatch onto the area you want to fill, and keep holding.
- Without lifting, slide left or right to change the Threshold. Left fills less, right fills more. The percentage shows at the top of the canvas.
- Lift your Apple Pencil or finger to commit the fill.
Procreate remembers your last Threshold, so you don't have to reset it for each fill.
Use Continue Filling for batches
After a ColorDrop, tap Continue Filling to fill other regions with simple taps. You can also tap, hold, and drag to adjust the Threshold between fills. Exit by tapping the tick at the top or switching to another tool, such as Paint.
On an iPad that supports Apple Pencil hover, you can hover over your current color in the top right and double-tap the side of the Pencil. This jumps straight into Continue Filling with that color.
When ColorDrop floods the whole layer
This is a common complaint. There are two usual causes:
- The Threshold is too high. Hold after the fill floods in, then slide left until the fill respects your lines.
- Your line art is on a different layer. ColorDrop reads the layer you're filling into, so a blank layer gives it nothing to stop at. Fix this with a Reference layer (see below).
Method 2: Reference layers for clean flats
If you keep line art on its own layer and paint color on layers underneath, you need a Reference layer.
- Open the Layers panel.
- Tap the line art layer's thumbnail to open Layer Options.
- Tap Reference.
- Select a new, empty layer beneath the line art.
- ColorDrop into the closed shapes. The fill is placed on your active layer but uses the line art to decide where to stop.
This keeps your line work untouched, so you can recolor, adjust, or replace fills later without redrawing anything. It matters most when you plan to animate or composite, because separate layers for line, flats, and shading are much easier to handle downstream.
Dealing with gaps and leaks
Procreate has no dedicated gap-closing setting like the ones in some dedicated inking and comic apps. If a line has even a small opening, color can escape into neighboring areas. Your options:
- Zoom in and close the gap with a small stroke on the line art layer.
- Lower the Threshold slightly and test again.
- Fill a nearby shape first to cut off the leak path, then fill the rest.
- Accept a slightly soft edge for illustrative work, or finish by hand where it matters.
Anti-aliased lines also leave a faint halo where the fill meets the edge. If you see one, try a slightly higher Threshold so the fill reaches under the soft pixels, or place your flats beneath the line art so the line covers the seam.
Method 3: Selections with Color Fill
If you prefer to define the area first and fill second, use Color Fill inside the Selections tool. It fills whatever you select with your current color as soon as the selection completes.
- Tap Selections at the top.
- Choose a method from the bottom tabs: Automatic, Freehand, Rectangle, or Ellipse.
- Tap Color Fill so it's highlighted blue.
- Choose your color in the top-right Colors icon.
- Make your selection. The fill appears right away.
This works well for geometric shapes, backgrounds, and masks. Combined with Feather, it also gives you soft-edged color areas, such as a vignette or a framing glow.
Two things to watch:
- Color Fill stays on. Procreate remembers the setting even after you leave Selections, so turn it off when you're done or your next selection will fill unexpectedly.
- It only works on a single layer. You can't Color Fill onto a group, so select an individual layer first.
Method 4: Fill Layer
When you want a solid background or a base color across a whole layer, Fill Layer is the quickest option.
- Pick your color.
- Open Layers and tap the target layer twice to open Layer Options.
- Tap Fill Layer.
Use this for background color layers, for color-block base layers you'll later modify with clipping masks, or to reset a layer to a flat color. It replaces the layer's contents, so duplicate the layer first if you might want the original back.
Method 5: Recolor through QuickMenu
Recolor is an older feature that Procreate brought back. It's off by default and only accessible from QuickMenu, which makes it easy to miss. It's an alternative to ColorDrop that some artists prefer.
To enable QuickMenu, go to Actions → Prefs → Gesture Controls → QuickMenu and choose how to invoke it. Then:
- Assign Recolor to one of the QuickMenu radial slots and tap it to enter the mode.
- Select your color in the top right.
- Tap the areas you want to fill.
- Adjust the Flood slider to control how aggressively the color spreads.
Recolor behaves much like ColorDrop with a Threshold, so the choice is mostly about preference and speed once it's set up in your gesture controls.
Choosing the right method
Tips that save time on real projects
- Separate your layers early. Line art, flats, shadows, and highlights on different layers are far easier to revise than a single flattened painting.
- Use clipping masks for shading. Once flats are down, clip shading layers to them so shadows can't spill outside the shapes.
- Use Alpha Lock for quick color changes. Locking a flat layer's transparency lets you repaint or fill it without touching the edges.
- Keep fill colors consistent. Build a palette first so you aren't picking colors by eye on each fill.
- Check edges at 100% and beyond. Fringing is hard to see zoomed out but shows up quickly when the art is scaled in a comp.
Getting Procreate flats into a motion pipeline
If you're an animator or motion designer, Procreate is often where you build style frames, character art, or textures that will end up in After Effects, Nuke, or Blender. A few practical habits help the handoff:
- Export layered files. Keep line art, flats, and shading as separate layers so you can animate or relight them as individual elements in After Effects.
- Export transparent PNGs for individual elements or frame sequences, so nothing has a baked-in background.
- Work at a high canvas resolution if the art will be scaled in a comp. Soft fill edges look worse when enlarged.
- Name layers clearly before export. Clear names save time when you're rebuilding the structure in a compositing app.
Procreate's fill tools automate the flat-coloring step for a single piece of art. They don't carry a look across a whole shot or sequence.
Quick troubleshooting
- Fill covers the whole layer: lower the Threshold, or set your line art as a Reference layer and fill on a separate layer.
- Color leaks out of a shape: close the gap in the line art, then refill.
- A halo shows around the fill: raise the Threshold slightly or put the flats beneath the line art.
- Color Fill isn't working on a group: select a single layer instead.
- Selections keep filling unexpectedly: turn Color Fill off in Selections.
- Recolor is missing: enable QuickMenu in Gesture Controls and assign Recolor to a radial slot.
Summary
For most work, the combination of ColorDrop with a tuned Threshold and a Reference layer gives the best balance of speed and cleanliness. Use Continue Filling to move quickly through many areas, Selections → Color Fill for geometric or feathered areas, and Fill Layer for backgrounds. Set up your layers cleanly from the start, and handing the artwork off to After Effects or Nuke becomes much easier.
