jQuery color is tested on the same browsers a jQuery Core 3.x versions. Check it
We release jQuery Color by itself, or in a bundle. The extended names can be included as a jQuery Color plugin, or you can download the version of jQuery Color that includes the names. Choose your build from the following list:
Current version: 2.1.2
- jQuery Color Compressed Uncompressed
- jQuery Color Extended Names Compressed Uncompressed
- jQuery Color & Extended Names(previous two combined) Compressed Uncompressed
First, get a copy of the git repo by running:
git clone git://github.com/jquery/jquery-color.git
Enter the directory and install the node dependencies:
cd jquery-color && npm install
Make sure you have grunt
installed by testing:
grunt -version
If not, run:
npm install -g grunt
To run tests locally, run grunt
, and this will run the tests in PhantomJS.
You can also run the tests in a browser by navigating to the test/
directory.
This plugins installs a cssHook
which allows jQuery's .animate()
to animate between two colors.

The jQuery.Color.hook()
function can be called to support additional css properties as colors, and allow them to be animated.
// we want to animate SVG fill and stroke properties
jQuery.Color.hook( "fill stroke" );
The jQuery.Color()
function allows you to create and manipulate color objects that are accepted by jQuery's .animate()
and .css()
functions.
- Returns a new Color object, similar to
jQuery()
orjQuery.Event
- Accepts many formats to create a new Color object with a
jQuery.Color.fn
prototype
// Parsing String Colors:
jQuery.Color( "#abcdef" );
jQuery.Color( "rgb(100,200,255)" );
jQuery.Color( "rgba(100,200,255,0.5)" );
jQuery.Color( "aqua" );
// Creating Color Objects in Code:
// use null or undefined for values you wish to leave out
jQuery.Color( red, green, blue, alpha );
jQuery.Color([ red, green, blue, alpha ]);
jQuery.Color({ red: red, green: green, blue: blue, alpha: alpha });
jQuery.Color({ hue: hue, saturation: saturation, lightness: lightness, alpha: alpha });
// Helper to get value from CSS
jQuery.Color( element, cssProperty );
red() // returns the "red" component of the color ( Integer from 0 - 255 )
red( val ) // returns a copy of the color object with the red set to val
green() // returns the "green" component of the color from ( Integer from 0 - 255 )
green( val ) // returns a copy of the color object with the green set to val
blue() // returns the "blue" component of the color from ( Integer from 0 - 255 )
blue( val ) // returns a copy of the color object with the blue set to val
alpha() // returns the "alpha" component of the color from ( Float from 0.0 - 1.0 )
alpha( val ) // returns a copy of the color object with the alpha set to val
hue() // returns the "hue" component of the color ( Integer from 0 - 359 )
hue( val ) // returns a copy of the color object with the hue set to val
saturation() // returns the "saturation" component of the color ( Float from 0.0 - 1.0 )
saturation( val ) // returns a copy of the color object with the saturation set to val
lightness() // returns the "lightness" component of the color ( Float from 0.0 - 1.0 )
lightness( val ) // returns a copy of the color object with the lightness set to val
// all of the above values can also take strings in the format of "+=100" or "-=100"
rgba() // returns a rgba "tuple" [ red, green, blue, alpha ]
// rgba() setters: returns a copy of the color with any defined values set to the new value
rgba( red, green, blue, alpha )
rgba({ red: red, green: green, blue: blue, alpha: alpha })
rgba([ red, green, blue, alpha ])
hsla() // returns a HSL tuple [ hue, saturation, lightness, alpha ]
// much like the rgb setter - returns a copy with any defined values set
hsla( hue, saturation, lightness, alpha )
hsla({ hue: hue, saturation: saturation, lightness: lightness, alpha: alpha )
hsla([ hue, saturation, lightness, alpha ])
toRgbaString() // returns a css string "rgba(255, 255, 255, 0.4)"
toHslaString() // returns a css string "hsla(330, 75%, 25%, 0.4)"
toHexString( includeAlpha ) // returns a css string "#abcdef", with "includeAlpha" uses "#rrggbbaa" (alpha *= 255)
The toRgbaString
and toHslaString
methods will only include the alpha channel if it is not 1
. They will return rgb(...)
and hsl(...)
strings if the alpha is set to 1
.
transition( othercolor, distance ) // the color distance ( 0.0 - 1.0 ) of the way between this color and othercolor
blend( othercolor ) // Will apply this color on top of the other color using alpha blending
is( othercolor ) // Will determine if this color is equal to all defined properties of othercolor
- Internally, RGBA values are stored as
color._rgba[0] = red, color._rgba[1] = green, color._rgba[2] = blue, color._rgba[3] = alpha
. However, please remember there are nice convenient setters and getters for each of these properties. undefined
/null
values for colors indicate non-existence. This signals thetransition()
function to keep whatever value was set in the other end of the transition. For example, animating tojQuery.Color([ 255, null, null, 1 ])
would only animate the red and alpha values of the color.
A list of named colors is stored on the jQuery.Color.names
object. The value they contain should be parseable by jQuery.Color()
. All names on this object should be lowercased. I.E. jQuery.Color("Red")
is the same as doing jQuery.Color( jQuery.Color.names["red"] );
There is also a named color "_default"
which by default is white, this is used for situations where a color is unparseable.
A special note about the color "transparent"
- It returns null
for red green and blue unless you specify colors for these values.
jQuery.Color("#abcdef").transition("transparent", 0.5)
Animating to or from the value "transparent"
will still use "#abcdef" for red green and blue.
If a color is created using any of the HSLA functions or parsers, it will keep the _rgba
array up to date as well as having a _hsla
array. Once an RGBA operation is performed on HSLA, however, the _hsla
cache is removed and all operations will continue based off of rgb (unless you go back into HSLA). The ._hsla
array follows the same format as ._rbga
, [hue, saturation, lightness, alpha ]
. If you need to build an HSLA color from an HSLA array, jQuery.Color().hsla( array )
works for that purpose.
Colors with 0 saturation, or 100%/0% lightness will be stored with a hue of 0
It is possible for you to add your own functions to the color object. For instance, this function will tell you if its better to use black or white on a given background color.
// method taken from https://gist.github.com/960189
jQuery.Color.fn.contrastColor = function() {
var r = this._rgba[0], g = this._rgba[1], b = this._rgba[2];
return (((r*299)+(g*587)+(b*144))/1000) >= 131.5 ? "black" : "white";
};
// usage examples:
jQuery.Color("#bada55").contrastColor(); // "black"
element.css( "color", jQuery.Color( element, "backgroundColor" ).contrastColor() );
