color

The color library contains static methods to help manipulate colors.

Installation

npm install --save @danehansen/color

Usage

As a module:

import * as color from '@danehansen/color';

var r = color.getRed(0xff0000);

In your browser:

<script src='danehansen-color.min.js'></script>
<script>
  var color = window.danehansen.color;
  var r = color.getRed(0xff0000);
</script>

Methods

• getRed(color:uint):uint
  Returns the red portion of a uint.
• getGreen(color:uint):uint
  Returns the green portion of a uint.
• getBlue(color:uint):uint
  Returns the blue portion of a uint.
• getUint(r:uint, g:uint, b:uint):uint
  Converts 3 uints into a single uint.
• distance({red:uint, green:uint, blue:uint}, {red:uint, green:uint, blue:uint}):Number
  Returns the "distance" between two color objects with red, green, and blue properties. The distance is an arbitrary value.
• sortColorsByHue(rgbs:Array):Array
  Approximately sorts a list of objects with red, green, and blue properties by their hue.
• getHSL(r:uint, g:uint, b:uint):Object
  Converts 3 uints into an object with hue, saturation, and lightness properties.
• getRGB(h:uint, s:Number, b:Number):Object
  Converts 3 numbers into an object with red, green, and blue properties.
• hexToUint(hex:String):uint
  Converts a hex in string format to a uint.
• getBrightness(r:uint, g:uint, b:uint):Number
  Returns the overall brightness of an RGB color as a single decimal between 0 and 1.
• getRGBString(r:uint, g:uint, b:uint, alpha:Number = 1):String
  Converts 3 uints into a 'rgba(X,X,X,X)' string.
• getHSLString(h:uint, s:Number, l:Number, alpha:Number = 1):String
  Converts 3 numbers into a 'hsla(X,X,X,X)' string.
• rgbStringToRGB(str:String):Object
  Converts a 'rgb' style string into an object with red, green, and blue properties.
• hslStringToHSL(str:String):Object
  Converts a 'hsl' style string into an object with hue, saturation, and lightness properties.
• getHex(color:uint):String
  Converts a uint into a '#XXXXXX' string.
• getHex({string:String, uint:uint, red:uint, green:uint, blue: uint, hue: uint, saturation: Number, lightness: Number}):Object
  Converts whatever you got into an object with red, green, blue, hue, saturation, lightness, brightness, rgb, hsl, uint, and hex properties.
