Readme

float-rgb2hsl
stable
Converts R,G,B to H,S,L.
var rgb2hsl = require('float-rgb2hsl')

var rgb = [0.375, 0.625, 0.625]

var hsl = rgb2hsl(rgb)
// -> [0.5, 0.25, 0.5]

All input/output uses the range 0 .. 1 for consistency and composition with other modules.

Usage

NPM

hsl = rgb2hsl(rgb)

Takes the rgb float array [R, G, B] and returns a [H, S, L] float representation.

Motivation

This was adapted from @harthur's wonderful color-convert module. Often I found myself only needing one function rather than all of them, and consistent input/output lends well to composition with other modules and WebGL.
