Fast Color Parsing and Manipulation

TinyColor

TinyColor is a small, fast library for color manipulation and conversion in JavaScript. It allows many forms of input, while providing color conversions and other color utility functions. It has no dependencies.

Download tinycolor.js or install it with bower:

bower install tinycolor

Then just include it in the page in a script tag:

<script type='text/javascript' src='tinycolor.js'></script>
<script type='text/javascript'>
var color = tinycolor("red");
</script>

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

npm install tinycolor2

Then it can be used in your script like so:

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

Call tinycolor(input) or new tinycolor(input), and you will have an object with the following properties. See Accepted String Input and Accepted Object Input below for more information about what is accepted.

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 for the S/L/V properties. The H (hue) can have values between 0%-100% or 0-360.

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

If you call tinycolor.fromRatio, RGB and Hue input can also accept 0-1.

Here are some examples of string input:

tinycolor("#000");
tinycolor("000");
tinycolor("#f0f0f6");
tinycolor("f0f0f6");
tinycolor("#88f0f0f6");
tinycolor("88f0f0f6");
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 });
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 });
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 });
tinycolor("RED");
tinycolor("blanchedalmond");
tinycolor("darkblue");

If you are calling this from code, you may want to use object input. Here are some 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 }

Return a boolean indicating whether the color was successfully parsed. Note: if the color is not valid then it will act like black when being used with other methods.

var color1 = tinycolor("red");
color1.isValid(); // true
color1.toHexString(); // "#ff0000"

var color2 = tinycolor("not a color");
color2.isValid(); // false
color2.toString(); // "#000000"

Return a boolean indicating whether the color's perceived brightness is light.

var color1 = tinycolor("#fff");
color1.isLight(); // true

var color2 = tinycolor("#000");
color2.isLight(); // false

Return a boolean indicating whether the color's perceived brightness is dark.

var color1 = tinycolor("#fff");
color1.isDark(); // false

var color2 = tinycolor("#000");
color2.isDark(); // true

Returns the alpha value of a color, from 0-1.

var color1 = tinycolor("rgba(255, 0, 0, .5)");
color1.getAlpha(); // 0.5

var color2 = tinycolor("rgb(255, 0, 0)");
color2.getAlpha(); // 1

var color3 = tinycolor("transparent");
color3.getAlpha(); // 0

Returns the perceived brightness of a color, from 0-255.

var color1 = tinycolor("#fff");
color1.getBrightness(); // 255

var color2 = tinycolor("#000");
color2.getBrightness(); // 0

Sets the alpha value on a current color. Accepted range is in between 0-1.

var color = tinycolor("red");
color.getAlpha(); // 1
color.setAlpha(.5);
color.getAlpha(); // .5
color.toRgbString(); // "rgba(255, 0, 0, .5)"
var color = tinycolor("red");
color.toHsv(); // { h: 0, s: 1, v: 1, a: 1 }
var color = tinycolor("red");
color.toHsvString(); // "hsv(0, 100%, 100%)"
var color = tinycolor("red");
color.toHsl(); // { h: 0, s: 1, l: 0.5, a: 1 }
var color = tinycolor("red");
color.toHslString(); // "hsl(0, 100%, 50%)"
var color = tinycolor("red");
color.toHex(); // "ff0000"
var color = tinycolor("red");
color.toHexString(); // "#ff0000"
var color = tinycolor("red");
color.toHex8(); // "ffff0000"
var color = tinycolor("red");
color.toHex8String(); // "#ffff0000"
var color = tinycolor("red");
color.toRgb(); // { r: 255, g: 0, b: 0, a: 1 }
var color = tinycolor("red");
color.toRgbString(); // "rgb(255, 0, 0)"
var color = tinycolor("red");
color.toPercentageRgb() // { r: "100%", g: "0%", b: "0%", a: 1 }
var color = tinycolor("red");
color.toPercentageRgbString(); // "rgb(100%, 0%, 0%)"
var color = tinycolor("red");
color.toName(); // "red"
var color = tinycolor("red");
color.toFilter(); // "progid:DXImageTransform.Microsoft.gradient(startColorstr=#ffff0000,endColorstr=#ffff0000)"

Print to a string, depending on the input format. You can also override this by passing one of "rgb", "prgb", "hex6", "hex3", "hex8", "name", "hsl", "hsv" into the function.

var color1 = tinycolor("red");
color1.toString(); // "red"
color1.toString("hsv"); // ""hsv(0, 100%, 100%)"

var color2 = tinycolor("rgb(255, 0, 0)");
color2.toString(); // "rgb(255, 0, 0)"
color2.setAlpha(.5);
color2.toString(); // "rgba(255, 0, 0, 0.5)"

These methods manipulate the current color, and return it for chaining. For instance:

tinycolor("red").lighten().desaturate().toHexString() // "#f53d3d"

lighten: function(amount = 10) -> TinyColor. Lighten the color a given amount, from 0 to 100. Providing 100 will always return white.

tinycolor("#f00").lighten().toString(); // "#ff3333"
tinycolor("#f00").lighten(100).toString(); // "#ffffff"

brighten: function(amount = 10) -> TinyColor. Brighten the color a given amount, from 0 to 100.

tinycolor("#f00").brighten().toString(); // "#ff1919"

darken: function(amount = 10) -> TinyColor. Darken the color a given amount, from 0 to 100. Providing 100 will always return black.

tinycolor("#f00").darken().toString(); // "#cc0000"
tinycolor("#f00").darken(100).toString(); // "#000000"

desaturate: function(amount = 10) -> TinyColor. Desaturate the color a given amount, from 0 to 100. Providing 100 will is the same as calling greyscale.

tinycolor("#f00").desaturate().toString(); // "#f20d0d"
tinycolor("#f00").desaturate(100).toString(); // "#808080"

saturate: function(amount = 10) -> TinyColor. Saturate the color a given amount, from 0 to 100.

tinycolor("hsl(0, 10%, 50%)").saturate().toString(); // "hsl(0, 20%, 50%)"

greyscale: function() -> TinyColor. Completely desaturates a color into greyscale. Same as calling desaturate(100).

tinycolor("#f00").greyscale().toString(); // "#808080"

spin: function(amount = 0) -> TinyColor. Spin the hue a given amount, from -360 to 360. Calling with 0, 360, or -360 will do nothing (since it sets the hue back to what it was before).

tinycolor("#f00").spin(180).toString(); // "#00ffff"
tinycolor("#f00").spin(-90).toString(); // "#7f00ff"
tinycolor("#f00").spin(90).toString(); // "#80ff00"

// spin(0) and spin(360) do nothing
tinycolor("#f00").spin(0).toString(); // "#ff0000"
tinycolor("#f00").spin(360).toString(); // "#ff0000"

Combination functions return an array of TinyColor objects unless otherwise noted.

analogous: function(, results = 6, slices = 30) -> array<TinyColor>.

var colors = tinycolor("#f00").analogous();

colors.map(function(t) { return t.toHexString(); }); // [ "#ff0000", "#ff0066", "#ff0033", "#ff0000", "#ff3300", "#ff6600" ]

monochromatic: function(, results = 6) -> array<TinyColor>.

var colors = tinycolor("#f00").monochromatic();

colors.map(function(t) { return t.toHexString(); }); // [ "#ff0000", "#2a0000", "#550000", "#800000", "#aa0000", "#d40000" ]

splitcomplement: function() -> array<TinyColor>.

var colors = tinycolor("#f00").splitcomplement();

colors.map(function(t) { return t.toHexString(); }); // [ "#ff0000", "#ccff00", "#0066ff" ]

triad: function() -> array<TinyColor>.

var colors = tinycolor("#f00").triad();

colors.map(function(t) { return t.toHexString(); }); // [ "#ff0000", "#00ff00", "#0000ff" ]

tetrad: function() -> array<TinyColor>.

var colors = tinycolor("#f00").tetrad();

colors.map(function(t) { return t.toHexString(); }); // [ "#ff0000", "#80ff00", "#00ffff", "#7f00ff" ]

complement: function() -> TinyColor.

tinycolor("#f00").complement().toHexString(); // "#00ffff"
tinycolor.equals(color1, color2)
tinycolor.mix(color1, color2, amount = 50)

readable: function(TinyColor, TinyColor) -> Object. 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("#000", "#111"); // {brightness: 17, color: 51}
tinycolor.readability("#000", "#fff"); // {brightness: 255, color: 765}

isReadable: function(TinyColor, TinyColor) -> Boolean. Ensure that foreground and background color combinations provide sufficient contrast.

tinycolor.isReadable("#000", "#111"); // false

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

tinycolor.mostReadable("#000", ["#f00", "#0f0", "#00f"]).toHexString(); // "#00ff00"
