Color-space

Collection of color spaces conversions & data.

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>.min //channel minimums
<space>.max //channel maximums
<space>.channel //channel names
<space>.alias //alias space names

Spaces

• RGB — additive color model based on red, green and blue primary colors.
• HSL — cylindrical-coordinates representation of RGB.
• HSV, HSB
• HWB
• HSI — used for computer vision due to better separation of shapes in an image, comparing to HSL/HSB.

Contribute

Please fork, add color space with basic conversions to/from XYZ or RGB and tests. The goal of the project is the most complete set of color spaces with minimal uniform API.

Thanks to all scientists, who devoted their time to color research and conveyed their knowledge, for now we can use their formulas and code.
