A library to generate distinct categorical colors, written in TypeScript.

Documentation

npm install @mapequation/c3

• Unlimited colors: Generate as many colors you want
• Any color scheme: We generate color stops on the interval [0, 1]. Perfect to use with d3.
• Deterministic: You always get the same colors for the same requested number of colors.
• Consistent: If you increase the number of colors, it doesn't change the list of colors you already have.
• Fast: The complexity is O(n log(n)) for n colors.

The algorithm is inspired by the Cantor set, which is a fractal that subdivides an interval recursively into smaller subsets.
