Color-space

Open collection of color spaces.

Demo.

Usage

1import space from 'color-space';
2
3//convert lab to lch
4var result = space.lab.lch([80,50,60]);

Spaces can be imported separately:

1import rgb from 'color-space/rgb.js';
2import hsl from 'color-space/hsl.js';
3
4//convert rgb to hsl
5rgb.hsl([200, 230, 100]);

API

1<fromSpace>.<toSpace>(array);
2<space>.name //space name
3<space>.channel //channel names
4<space>.min //channel minimums
5<space>.max //channel maximums

Spaces

• RGB — sRGB
• LRGB – linear light sRGB
• HSL — cylindrical-coordinates sRGB
• HSV, HSB
• HWB
• HSI — used for computer vision due to better separation of shapes in an image, comparing to HSL/HSB.
• CMYK
• CMY
• XYZ
• XYY (YXY)
• LAB
• LCH_ab
• LUV
• LCH_uv
• HSL_uv

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.
