TinyColor

JavaScript color parsing

Fast, small color manipulation and conversion for JavaScript. TinyColor is allows many forms of input, while providing color conversions and other color utility functions. It has no dependancies.

Supported Color Types

Hex, 8-digit (ARGB) Hex

tinycolor("#000");
tinycolor("000");
tinycolor("#f0f0f6");
tinycolor("f0f0f6");
tinycolor("#88f0f0f6");
tinycolor("88f0f0f6");

RGB, RGBA

tinycolor("rgb (255, 0, 0)");
tinycolor("rgb 255 0 0");
tinycolor("rgba (255, 0, 0, .5)");
tinycolor({ r: 255, g: 0, b: 0 });
tinycolor.fromRatio({ r: 1, g: 0, b: 0 });
tinycolor.fromRatio({ r: .5, g: .5, b: .5 });

HSL, HSLA

tinycolor("hsl(0, 100%, 50%)");
tinycolor("hsla(0, 100%, 50%, .5)");
tinycolor("hsl(0, 100%, 50%)");
tinycolor("hsl 0 1.0 0.5");
tinycolor({ h: 0, s: 1, l: .5 });

HSV, HSVA

tinycolor("hsv(0, 100%, 100%)");
tinycolor("hsva(0, 100%, 100%, .5)");
tinycolor("hsv (0 100% 100%)");
tinycolor("hsv 0 1 1");
tinycolor({ h: 0, s: 100, v: 100 });

Named

tinycolor("RED");
tinycolor("blanchedalmond");
tinycolor("darkblue");

Using in a browser

<script type='text/javascript' src='tinycolor.js'></script>
<script type='text/javascript'>
var t = tinycolor("red");

t.toHex() // "ff0000"
t.toHexString() // "#ff0000"
t.toHex8() // "ffff0000"
t.toHex8String() // "#ffff0000"
t.toRgb() // {"r":255,"g":0,"b":0} or {"r":255,"g":0,"b":0,"a":0.5}
t.toRgbString() // "rgb(255, 0, 0)" or "rgba(255, 0, 0, 0.5)"
t.toPercentageRgb() // {"r":100,"g":0,"b":0} or {"r":100,"g":0,"b":0,"a":0.5}
t.toPercentageRgbString() // "rgb(100%, 0%, 0%)" or "rgba(100%, 0%, 0%, 0.5)"
t.toHsv() // {"h":0,"s":1,"v":1}
t.toHsvString() // "hsv(0, 100%, 100%)"
t.toHsl() // {"h":0,"s":1,"l":0.5}
t.toHslString() // "hsl(0, 100%, 50%)"
t.toName() // "red"
t.toString(/* format */) // "red"
t.toFilter()
</script>

Using in node

tinycolor may also be included as a node module like so:

npm install tinycolor2

Then it can be used:

var tinycolor = require("./tinycolor");

Accepted String Input

The string parsing is very permissive. It is meant to make typing a color as input as easy as possible. All commas, percentages, parenthesis are optional, and most input allow either 0-1, 0%-100%, or 0-n (where n is either 100, 255, or 360 depending on the value).

HSL and HSV both require either 0%-100% or 0-1.

RGB input requires either 0-255 or 0%-100%.

If you call tinycolor.fromRatio, RGB input can also accept 0-1 Here are some examples of string input:

red
#fff
fff
#ffffff
ffffff
#ffffffff
ffffffff
rgb(255, 0, 0)
rgb 255 0 0
hsl(0, 100, 50)
hsl(0, 100%, 50%)
hsl 0 100 50
hsl 0 100% 50%
hsv(0, 100%, 100%)
hsv(0, 100, 100)
hsv 0 100% 100%
hsv 0 100 100

Accepted Object Input

If you are calling this from code, you may want to use object input. Here are examples of the different types of accepted object inputs:

{ r: 255, g: 0, b: 0 }
{ r: 255, g: 0, b: 0, a: .5 }
{ h: 0, s: 100, l: 50 }
{ h: 0, s: 100, v: 100 }
// etc...

Color Utilities

tinycolor.equals(color1, color2)

Color Modification

Modification functions may take an amount variable from 0 - 100, indicating how much the effect should be applied.

tinycolor.lighten(color, amount = 10)
tinycolor.darken(color, amount = 10)
tinycolor.desaturate(color, amount = 10)
tinycolor.saturate(color, amount = 10)
tinycolor.greyscale(color)

Color Combinations

Combination functions return an Array of TinyColor objects.

tinycolor.analogous(color, results = 6, slices = 30)
tinycolor.complement(color)
tinycolor.monochromatic(color, results = 6)
tinycolor.splitcomplements(color)
tinycolor.triad(color)
tinycolor.tetrad(color)

Readability

Analyze 2 colors and returns an object with the following properties. brightness is difference in brightness between the two colors. color: difference in color/hue between the two colors.

tinycolor.readability(color1, color2);

Ensure that foreground and background color combinations provide sufficient contrast.

tinycolor.readable(color1, color2);

Given a base color and a list of possible foreground or background colors for that base, returns the most readable color.

tinycolor.mostReadable(baseColor, colorList);

See index.html in the project for a demo.
