Human-friendly HSL.

To install, run:

haxelib install hsluv 0.0.1 

See using Haxelib in Haxelib documentation for more information.


Reference implementation


Once imported, use the library by importing Hsluv. Here's an example:

import hsluv.Hsluv;

public class Main {
    public static function main() {
        trace(Hsluv.rgbToHex([1,1,1])); // Will print "#FFFFFF"

Color values ranges

  • RGB values are ranging in [0;1]
  • HSLuv and HPLuv values have different ranging for their components - H : [0;360] - S and L : [0;100]
  • LUV has different ranging for their components - L : [0;100] - u and v* : [-100;100]
  • LCh has different ranging for their components - L : [0;100] - C : [0; ?] Upper bound varies depending on L and H - H* : [0; 360]
  • XYZ values are ranging in [0;1]

API functions


The passing/returning values, when not String are Array<Float> containing each component of the given color space/system in the name's order : - RGB : [red, blue, green] - XYZ : [X, Y, Z] - LCH : [L, C, H] - LUV : [L, u, v] - HSLuv/HPLuv : [H, S, L]

This code work on some targets, but here are some tests that couldn't pass on my computer: - PHP : PHP7 parseInt function doesn't convert hexadecimal values anymore.

Tests to do: - SWF - Windows and Mac
