Named

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

Usage

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"

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 requires either 0-255 or 0%-100%. If you call tinycolor.fromRatio, any 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 }
{ r: 1, g: 0, b: 0 }
{ 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.
