Create color scales by rotating hue

color-harmony

Description

A javascript library that creates color scales/harmonies by rotating the hue of the given color.

There are also helper methods to create shades (mixing w/ black), tints (mixing w/ white), and tones (mixing w/ middle gray).

Getting Started

Install the module with: npm install color-harmony

var Harmonizer = require('color-harmony').Harmonizer;
var harmonizer = new Harmonizer();
harmonizer.harmonizeAll('#c820f1'); // returns a map of scales
harmonizer.harmonize('#000', 'complementary'); // returns ['#000000', '#ffffff']

Documentation

This library uses the onecolor parser, so colorString can in many different formats (i.e. #ff00cc, rgb(13,42,255), etc).

harmonizer.add(harmonyName, degreeArray)

Add a new named harmony. If the harmony name already exists, it will be overwritten. If degreeArray is not an array of numbers, then the harmony will not be added.

harmonizer.harmonizeAll(colorString)

Return a map of all the harmonies for the given color string.

harmonizer.harmonize(colorString, harmony)

Return an array of hex codes based on the given color string and harmony.

The harmony argument can be a 'named harmony', or it can be a custom harmony by passing in an array of numbers (degrees 0-360).

harmonizer.shades(colorString, size)

Return an array of hex codes container the shades of a given color (i.e. mix it with black - #000000).

If size is not a valid number, then the array will default to a size of 10.

harmonizer.tints(colorString, size)

Return an array of hex codes container the tints of a given color (i.e. mix it with white - #FFFFFF).

If size is not a valid number, then the array will default to a size of 10.

harmonizer.tones(colorString, size)

Return an array of hex codes container the tones of a given color (i.e. mix it with middle gray - #777777).

If size is not a valid number, then the array will default to a size of 10.

Examples

Get all the stored harmonies

harmonizer.harmonizeAll('#c820f1'); // returns a map of scales

Get a named harmony

harmonizer.harmonize('#000', 'complementary'); // returns ['#000000', '#ffffff']

Get a custom harmony

harmonizer.harmonize('#000', [0, 10, 20, 30, 40]); // returns an array of colors

Add a custom harmony that can later be referenced by name

harmonizer.add('foo', [0, 25, 45]);
harmonizer.harmonize('#00cc00', 'foo'); // returns your custom data

Return the shades of a given color (mix it with black - #000000)

harmonizer.shades('#925719'); // returns 10 by default
harmonizer.shades('#925719', 14); // you can return a custom amount (an array of 14)

Return the tints of a given color (mix it with white - #FFFFFF)

harmonizer.tints('#925719'); // returns 10 by default
harmonizer.tints('#925719', 14); // you can return a custom amount (an array of 14)

Return the tones of a given color (mix it with middle gray - #777777)

harmonizer.tones('#925719'); // returns 10 by default
harmonizer.tones('#925719', 14); // you can return a custom amount (an array of 14)
