Color Machine

Color Machine is a tool for creating color palettes. It uses a self-organizing map to generate new color palettes.

Usage

npm install
node random-palettes.js 4000 > palettes.json
node color-machine.js palettes.json
open color-machine.png

Palette Format

Palettes are expressed as a set of RGB colors. Each color has the format [red, green, blue, weight]. The red, green, and blue components are in the range 0 to 255. The weight component is in the range 0 to 1; it's the percentage of space in the palette the color takes up.
