Package Exports

picolor-js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (picolor-js) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

picolor.js

JavaScript color picker for picking colors in LCH space. It is optimized for picking visually distinct colors for maps, but can be used for anything else.

Why not use a stock color picker?

Picking suitable colors for maps are hard, especially when it comes to selecting visually distinct colors for a range of values. picolor.js aims to ease that process by providing smart pre-set visually distinct colors and palettes.
