Brush Tool

Paint with a soft, round brush for expressive, flowing strokes. Great for colouring large areas, shading, and artistic effects.

How to use the Brush

Select the Brush tool from the toolbar. The context panel shows a Size slider.

Choose your colour from the colour picker or sample a colour from the canvas with the Eye Dropper.

Set brush size using the slider (1-100 px). Larger sizes create bold, sweeping strokes. Default is 10 px .

Paint on the canvas. Click and drag to apply paint. The brush produces soft-edged strokes that blend with the background.

Release to finish. Lift your pointer to end the stroke. Start another stroke immediately.

Brush features

Soft edges

The brush applies a radial gradient falloff, creating smooth anti-aliased edges that look natural rather than pixelated.

Wide coverage

Ideal for quickly filling large areas. Set size to 40-80 px for background colour blocking.

Layering

Paint multiple strokes over the same area to build up richer, denser colour.

Brush vs Pencil: The Brush produces wide, soft strokes. For precise outlines use the Pencil; for shading and colouring large areas use the Brush.

Tips

Build up colour gradually

Start with fast strokes for a light wash, then layer slower strokes over the same area to create depth and shading.

Large brush for backgrounds

Use size 40-80 px to quickly cover large areas before adding fine detail on top.

Combine with Eraser

Use a large brush to block in colour, then a smaller eraser to refine edges and create clean shapes.
