Start from a built-in motif, or drop your own (a PNG with transparency works best — a flower, an octopus, your logo).

Five colours make the pattern. For the multicolour-circles motif four become the circles and one the background — Shuffle, or Generate colourways below, reshuffles all five, so the background is always one of your colours and never a repeat of a circle.

Seamless preview — what you see tiles edge to edge. Export the single repeat tile to drop into any other tool.

Spin the same pattern into a set of colourways — from the colours above by default, or paste a list / pull your Palette Hub palette to use those instead. Click a result to apply it.
