Color-space

Open collection of color spaces.

Demo.

Usage

import space from 'color-space';

//convert lab to lch
var result = space.lab.lch([80,50,60]);

Spaces can be imported separately:

import rgb from 'color-space/rgb.js';
import hsl from 'color-space/hsl.js';

//convert rgb to hsl
rgb.hsl([200, 230, 100]);

API

<fromSpace>.<toSpace>(array);
<space>.name //space name
<space>.channel //channel names
<space>.min //channel minimums
<space>.max //channel maximums

Purpose

A complete collection of color spaces with minimal consistent and clean API, verified formulas and cases. While alternatives focus on digital color spaces, this project takes broader perspective, including historical / multidisciplinary spaces. A side effect is verifying and correcting papers.
