Style Tool
Apply fill styles and colours to individual polygons or groups.

Each polygon can use one or more styles at the same time. Enable the styles you want in the panel, pick a colour for each, and click a polygon to apply.
- Solid — fills the polygon with a solid colour.
- Outline — draws only the polygon border.
- Center to Vertices — draws lines from the centre to each vertex.
- Center to Midpoints — draws lines from the centre to each edge midpoint.

Enable multiple styles at the same time to layer them on a single polygon. All checked styles are applied together when you click.

Apply a style to all polygons of the same type at once. For example, clicking a hexagon restyles every hexagon on the canvas while leaving squares unchanged.

Apply a style to all polygons that currently share the same style, regardless of shape. For example, clicking any blue solid polygon restyles every blue solid polygon on the canvas.

The Apply All button applies the currently selected style and colour to every polygon on the canvas at once.
