To ColorDrop in Procreate, drag the active color swatch from the top-right corner of the canvas and release it inside a closed shape. Procreate floods that area until it hits an outline. If the fill spills across the canvas or leaves gaps, hold your finger or Pencil on the screen after dropping, watch for the blue Threshold bar, and slide left to fill less or right to fill more before you lift.

Basic ColorDrop: Fill a Closed Shape

ColorDrop works like a bucket tool. It's faster than painting a large area with a brush, and it handles edges more cleanly.

1. Select the layer you want to fill. By default, ColorDrop reads the line work on the same layer it fills.
2. Pick your color in the Colors panel.
3. Touch the color circle in the top-right corner, drag it onto the canvas, and release inside the shape.

You can also drag a swatch straight from a palette if the palette is floating. That's handy when your fill color differs from your outline color and you don't want to change the active color first.

The one hard requirement is a closed shape. If your outline has even a tiny gap, the color escapes through it and floods the whole canvas. If that happens, two-finger tap to undo, close the gap with a brush stroke, and try again.

Adjust the ColorDrop Threshold

Threshold controls how much of the surrounding area the fill is allowed to flood. It matters most when your lines are soft, textured, or not perfectly closed.

1. Drag the color into your shape, but don't lift your finger or Pencil.
2. Hold still for a moment until a thin blue bar and a percentage readout appear at the top of the canvas.
3. Without breaking contact with the screen, slide left to lower the percentage (less fill) or right to raise it (more fill).
4. Lift to commit the fill.

A few details trip people up:

• You don't need to touch the slider itself. Moving your finger or Pencil left or right anywhere on the screen adjusts it.
• Use one hand and one input. If you hold the color with a Pencil and try to swipe with a finger, you can break the continuous contact the adjustment needs.
• The readout should show a percentage. If it doesn't appear, the Threshold hasn't activated, so hold a little longer before moving.
• Procreate remembers your last Threshold. If a fill suddenly behaves differently from the last one, the old setting is probably still active.

Keep Fills on a Separate Layer with Reference

Filling on the same layer as your line art is quick, but it's destructive. Color and lines end up merged, which is a nuisance when you want to recolor later or export separate elements.

The cleaner approach is to use the Reference feature:

1. Open the Layers panel.
2. Tap the thumbnail of your line art layer to open its options.
3. Tap Reference.
4. Create a new layer underneath, select it, and ColorDrop into the shapes.

Procreate now reads the outlines from the Reference layer but puts the color on the layer you're working on. Your line art stays untouched, and you can adjust, swap, or hide the color layer freely.

Fix ColorDrop Filling the Whole Canvas

If you've closed your shape and the entire canvas still turns one color, work through these causes in order.

1. Check for gaps

Zoom in on the outline. Hairline breaks are easy to miss, especially on shapes drawn quickly or cleaned up with an eraser. Draw over the suspect area with a hard brush to seal it.

2. Check the Threshold

A Threshold of 100% will flood nearly everything. Hold the drop, wait for the blue bar, and slide left until the fill stays inside the shape. Because Procreate remembers the setting, this is a frequent cause when fills worked earlier in the session and suddenly don't.

3. Look for a stray Reference layer

This catches a lot of artists. If any layer has Reference turned on, ColorDrop reads from it instead of the layer you're filling. That layer may be in a completely different group, so check every layer, not just the visible ones. Turn off Reference on layers you aren't using as line art.

4. Merge split outlines

If your outline is spread across several layers, ColorDrop may only read one of them, leaving gaps in what it can see. Merge the outline layers into one, or merge them before setting the result as Reference.

5. Restart if the drop does nothing at all

Some users report that dragging a color occasionally does nothing, particularly after filling a blank layer and then trying a second color. If the color circle isn't being picked up, closing the app or returning to the Gallery and reopening the canvas usually clears it. If it keeps happening, update Procreate and iPadOS, since this behavior has been reported as an intermittent bug rather than a technique problem.

Fill Textured or Sketchy Lines

Textured brushes like chalk have grain, light patches, and tiny gaps. A ColorDrop will often leave unfilled flecks along the edge, because the fill treats those lighter pixels as part of the outline.

Raise the Threshold slowly while holding the drop. Increase it a few percentage points at a time until the gaps fill, then lift. Even then, expect some visible difference between a flat fill and a textured stroke. For stylized work, that mismatch can look intentional. For clean shapes, draw your outline with a hard, solid brush (a monoline brush works well) and keep texture on a separate layer.

Useful Workflow Tips

• Use a hard-edged outline brush for any shape you plan to ColorDrop. Soft brushes produce soft edges that fill unpredictably.
• Keep line art, flats, and shading on separate layers. Reference plus ColorDrop gives you flats that you can recolor without redrawing.
• Use two-finger tap to undo immediately when a fill goes wrong, rather than painting over it.
• Name your layers. When you need to find the layer that has Reference enabled, clear names save time.

Using Procreate Flats in a Motion Pipeline

Some motion designers use Procreate for boards, character designs, textures, and styleframes before moving to other tools such as After Effects, Cinema 4D, Blender, or Nuke. ColorDrop is part of that: flat fills on a separate layer give you clean shapes to animate, track mattes to build, or palettes to hand off.

A few practical habits make that handoff easier:

• Keep flats and lines separate so you can handle them independently when you export.
• Work at the final resolution you need. Upscaling a small flat illustration later can soften the edges you worked to seal.
• Name layers for the compositor. Clear layer names make the handoff easier.
• Check your color workflow. Confirm your colors match your project before building a grade around them.

Quick Reference

Final Thoughts

ColorDrop is simple once you know its three parts: a closed shape, a Threshold you control by holding the drop, and an optional Reference layer to keep fills off your line art. Common problems include a small gap, a Threshold left too high, or a forgotten Reference layer on a different layer. Check those first, keep your layers organized, and your flats will carry cleanly into whatever animation or compositing pipeline comes next.
