This Demonstration lets you create your own piece of colorful abstract art by using the colors of the rainbow ("hues") in many ways. Cutouts from circles (called "arcs") show colors that spread over a wide range and flow into each other.

You can choose between a semiautomatic drawing (select "auto") or more hands-on control (select "disk" or "from-to"). Eight vertices are placed on the "canvas" (controlled by your mouse), and one rainbow-colored arc and one monochrome-colored round dot are placed at each vertex.
