RanCol - A random color generator

This small program is a node module for the generation of random color codes in HEX and RGB format.

Usage

HEX colors

var rancol = require('rancol');

console.log( rancol.hex() );

RGB(A) colors

RGB colors have two formats, one is a numeric representation of an 8-bit channel (0-255) and the other one is percentual (0-100). Transparency is provided through the alpha channel (0.0 - 1.0).

rancol.rgb()     // "rgb(2, 172, 55);"
rancol.rgba()    // "rgba(244, 175, 148, 0.6);"
rancol.rgbp()    // "rgb(82%, 3%, 34%);"
rancol.rgbpa()   // "rgba(46%, 21%, 57%, 0.0);"

HSL(A) colors

rancol.hsl()     // "hsl(18, 38%, 96%);"
rancol.hsla()    // "hsla(114, 17%, 90%, 0.7);"

Keyword colors

The CSS specification allows some colours to be named with a keyword, and rancol offers the possibiltiy to use these keywords for random color generation.

Rancol supports the complete list of basic and extednded color keywords that can be found here: http://www.w3.org/wiki/CSS/Properties/color/keywords

rancol.keyword()  // "maroon"

Command line usage

Rancol cal also be used from the comamnd line. The various flags are named after the functions, so a valid example of running rancol could be:

$ rancol --rgba

rgba(201, 244, 125, 0.7);
