JavaScript CIE-1931-rgb-color-converter

A simple JS lib for converting rgb to cie1931 (Which Philips HUE Color lights use) and vice versa.

• NO dependency
• Automatically adjusts Colors based on light capability
• Color correction supports a range of Philips Hue lights
• ECMAScript 6
• Easy to use

This lib was made with the help of the Philips Hue Docs.

Note: Color accuracy can differ depening on light capabilites.

Installation

Download the script here and include it (unless you are packaging scripts somehow else)

<script type="module" src="path/to/ColorConverter.js"></script>

And then import it inside your js

Import ColorConverter from "path/to"

Do not include the script directly from GitHub (http://raw.github.com/...). The file is being served as text/plain and as such being blocked in Internet Explorer on Windows 7 for instance (because of the wrong MIME type). Bottom line: GitHub is not a CDN.

NPM

npm install cie-rgb-color-converter

Usage

Convert RGB to XY for Philips Hue lights

let xy = ColorConverter.rgbToXy(red, green, blue, light.modelid);
// xy = {x: xValue, y: yValue};

Convert RGB to XY for non Philips lights

let xy = ColorConverter.rgbToXy(red, green, blue);
// xy = {x: xValue, y: yValue};

Note: Colors may be off due to gamut capabilities of the Light. This setting uses a default gamut range provided by Philips Hue Docs. This may exceed the lights capabilities, resulting in wrong colors depending on lights behaviour.

Convert XY + bightness to RGB

let rgb = ColorConverter.xyBriToRgb(x ,y , brightness);
// rgb =  {r: redValue, g: greenValue, b: blueValue}
