Installation

npm install easy-color

How to use

Import the module and create an instance of the constructor by placing the color you want to convert
You can put in any supported format
Example:

var Color = require('easy-color');
// Instance
var parser = new Color("#00AAFF"); // You can also add: # 0af, rgb (0, 170, 255), hsl (..., etc ...

// Converta
parser.toHEX();  // Converts to HEX format   (Hexadecimal)
parser.toRGB();  // Converts to RGB format  (Red, Green, Blue)
parser.toRGBA(); // Converts to RGBA format (Red, Green, Blue, Alpha)
parser.toHSL();  // Converts to HSL format  (Hue, Saturation, Lightness)
parser.toHSLA(); // Converts to HSLA format (Hue, Saturation, Lightness, Alpha)
parser.toCMYK(); // Converts to CMYK format (Cyan, Magenta, Yellow, Key)

To convert the values of a color separately use:

// RGB
var parser = new Color.fromRGB(0, 170, 255); // Values
var parser = new Color.fromRGB([0, 170, 255]); // Array of values
var parser = new Color.fromRGB({ r: 0, g: 170, b: 255 }); // Object of values

// RGBA
var parser = new Color.fromRGBA(0, 170, 255, 1); // Values
var parser = new Color.fromRGBA([0, 170, 255, 1]); // Array of values
var parser = new Color.fromRGBA({ r: 0, g: 170, b: 255, a: 1 }); // Object of values

// HSL
var parser = new Color.fromHSL(200, 100, 50); // Values
var parser = new Color.fromHSL([200, 100, 50]); // Array of values
var parser = new Color.fromHSL({ h: 200, s: 100, l: 50 }); // Object of values

// HSLA
var parser = new Color.fromHSLA(200, 100, 50, 1); // Values
var parser = new Color.fromHSLA([200, 100, 50, 1]); // Array of values
var parser = new Color.fromHSLA({ h: 200, s: 100, l: 50, a: 1 }); // Object of values

// CMYK
var parser = new Color.fromCMYK(100, 33, 0, 0); // Values
var parser = new Color.fromCMYK([100, 33, 0, 0]); // Array of values
var parser = new Color.fromCMYK({ c: 100, m: 33, y: 0, k: 0 }); // Object of values

-- You can also get the name of the color format that you have set to make it easier in some cases

parser.colorType(); // Returns the color format defined

-- So you can also convert a color to a format from the format name

parser.to("RGBA") // In this case it will return the color value in RGBA format, eg rgba (0, 170, 255, 1)

CSS Color Table

You can pick up the CSS color table used to convert the color name to HEX, eg: white -> #FFFFFF
Read about CSS Color Table
To get the array of this table use:

var table = parser.CSSColorTable;

With this table you can convert colors just by name too
For example:

var parser = new EasyColorParser("aqua"); // Creates the instance from the css color name
parser.toHex(); // #00FFFF

--

Values

To get the separate values for each format use:

var rgb = parser.rgb,     // Returns an array with the RGB values  ->  {r:Number, g:Number, b:Number}
    hsl = parser.hsl,     // Returns an array with the HSL valuesL ->  {h:Number, s:Number, l:Number}
    cmyk = parser.cmyk,   // Returns an array with the CMYK values ->  ...
    alpha = parser.alpha; // Returns color transparency            ->  1

// RGB
var red = rgb.r;
var green = rgb.g;
var blue = rgb.b;

// HSL
var hue = hsl.h;
var saturation = hsl.s;
var lightness = hsl.l;

// CMYK
var cyan = cmyk.c;
var magenta = cmyk.m;
var yellow = cmyk.y;
var key = cmyk.k;
