Stained Glass Mosaic Coloring Page

About this geometric pattern coloring page

Irregular polygons of different sizes fill this page like pieces of a stained glass window or a cracked mosaic. The shapes come from a Voronoi diagram, a mathematical way of dividing space around scattered points, which gives a natural, organic feel even though every cell is straight-edged. There are 140 regions, a medium page with comfortably large cells. There is no symmetry and no right answer: you can color randomly, create gradients that sweep across the page, or hide a simple picture such as a sunset or a heart by choosing colors for groups of cells.

Coloring tips

Try a sweep: start with yellow in one corner and move through orange and red to purple in the opposite corner, choosing each cell's color by where it sits. Or make a mosaic with five jewel tones and a rule that neighbors never match. A dark grey background in a few scattered cells adds depth like lead lines in real glass.
