TinyColor-PHP is a TinyColor implementation written in PHP

Install

Via Composer

$ composer require tinycolor/tinycolor

Usage

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

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 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\TinyColor::fromRatio, RGB and Hue input can also accept 0-1.

Here are some examples of string input:

Hex, 8-digit (RGBA) Hex

tinycolor("#000");
tinycolor("000");
tinycolor("#369C");
tinycolor("369C");
tinycolor("#f0f0f6");
tinycolor("f0f0f6");
tinycolor("#f0f0f688");
tinycolor("f0f0f688");

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\TinyColor::fromRatio(['r' => 1, 'g' => 0, 'b' => 0]);
\TinyColor\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]);
\TinyColor\TinyColor::fromRatio(['h' => 1, 's' => 0, 'l' => 0]);
\TinyColor\TinyColor::fromRatio(['h' => .5, 's' => .5, '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]);
\TinyColor\TinyColor::fromRatio(['h' => 1, 's' => 0, 'v' => 0]);
\TinyColor\TinyColor::fromRatio(['h' => .5, 's' => .5, 'v' => .5]);

Named

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

Accepted Array Input

If you are calling this from code, you may want to use array input. Here are some examples of the different types of accepted array 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]

Methods

getFormat

Returns the format used to create the tinycolor instance

$color = tinycolor("red");
$color->getFormat(); // "name"
$color = tinycolor(['r' => 255, 'g' => 255, 'b' => 255]);
$color->getFormat(); // "rgb"

getOriginalInput

Returns the input passed into the constructer used to create the tinycolor instance

$color = tinycolor("red");
$color->getOriginalInput(); // "red"
$color = tinycolor(['r' => 255, 'g' => 255, 'b' => 255]);
$color->getOriginalInput(); // "['r' => 255, 'g' => 255, 'b' => 255]"

isValid

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.

$color1->isValid(); // true
$color1->toHexString(); // "#ff0000"

$color2 = tinycolor("not a color");
$color2->isValid(); // false

$color1 = tinycolor("#fff");
$color1->getBrightness(); // 255

$color2 = tinycolor("#000");
$color2->getBrightness(); // 0

isLight

$color->getAlpha(); // 1
$color->setAlpha(.5);
$color->getAlpha(); // .5
$color->toRgbString(); // "rgba(255, 0, 0, .5)"

String Representations

The following methods will return a property for the alpha value, which can be ignored: toHsv, toHsl, toRgb

$color1 = tinycolor("red");
$color1->toString(); // "red"
$color1->toString("hsv"); // "hsv(0, 100%, 100%)"

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

Color Modification

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

tinycolor("red")->lighten()->desaturate()->toHexString(); // "#f53d3d"

lighten

lighten: function($amount = 10) -> TinyColor\Color. 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

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

tinycolor("#f00")->brighten()->toString(); // "#ff1919"

darken

darken: function($amount = 10) -> TinyColor\Color. 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

desaturate: function($amount = 10) -> TinyColor\Color. 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

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

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

greyscale

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

tinycolor("#f00")->greyscale()->toString(); // "#808080"

spin

spin: function($amount = 0) -> TinyColor\Color. 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"

Color Combinations

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

analogous

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

$colors = tinycolor("#f00")->analogous();
array_map(function ($t) { return $t->toHexString();}, $colors); // [ "#ff0000", "#ff0066", "#ff0033", "#ff0000", "#ff3300", "#ff6600" ]

monochromatic

monochromatic: function($results = 6) -> array<TinyColor\Color>.

$colors = tinycolor("#f00").monochromatic();
array_map(function ($t) { return $t->toHexString();}, $colors); // [ "#ff0000", "#2a0000", "#550000", "#800000", "#aa0000", "#d40000" ]

splitcomplement

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

$colors = tinycolor("#f00").splitcomplement();
array_map(function ($t) { return $t->toHexString();}, $colors); // [ "#ff0000", "#ccff00", "#0066ff" ]

triad

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

$colors = tinycolor("#f00")->triad();
array_map(function ($t) { return $t->toHexString();}, $colors); // [ "#ff0000", "#00ff00", "#0000ff" ]

tetrad

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

$colors = tinycolor("#f00")->tetrad();
array_map(function ($t) { return $t->toHexString();}, $colors); // [ "#ff0000", "#80ff00", "#00ffff", "#7f00ff" ]

complement

complement: function() -> TinyColor\Color.

tinycolor("#f00")->complement()->toHexString(); // "#00ffff"

Color Utilities

\TinyColor\TinyColor::equals($color1, $color2);
\TinyColor\TinyColor::mix($color1, $color2, $amount);

random

Returns a random color.

$color = \TinyColor\TinyColor::random();
$color->toRgb(); // "['r' => 145, 'g' => 40, 'b' => 198, 'a' => 1]"

Readability

TinyColor assesses readability based on the Web Content Accessibility Guidelines (Version 2.0).

readability

readability: function(TinyColor\Color, TinyColor\Color) -> Number. Returns the contrast ratio between two colors.

\TinyColor\TinyColor::readability("#000", "#000"); // 1
\TinyColor\TinyColor::readability("#000", "#111"); // 1.1121078324840545
\TinyColor\TinyColor::readability("#000", "#fff"); // 21

Use the values in your own calculations, or use one of the convenience functions below.

isReadable

isReadable: function(TinyColor\Color, TinyColor\Color, Array) -> Boolean. Ensure that foreground and background color combinations meet WCAG guidelines. Array is optional, defaulting to ['level' => "AA",'size' => "small"]. level can be "AA" or "AAA" and size can be "small" or "large".

Here are links to read more about the AA and AAA requirements.

\TinyColor\TinyColor::isReadable("#000", "#111", []); // false
\TinyColor\TinyColor::isReadable("#ff0088", "#5c1a72",['level' => "AA",'size' => "small"]); //false
\TinyColor\TinyColor::isReadable("#ff0088", "#5c1a72",['level' => "AA",'size' => "large"]); //true

mostReadable

mostReadable: function(TinyColor\Color, [TinyColor\Color, Tinycolor\Color ...], Array) -> Boolean. Given a base color and a list of possible foreground or background colors for that base, returns the most readable color. If none of the colors in the list is readable, mostReadable will return the better of black or white if includeFallbackColors:true.

\TinyColor\TinyColor::mostReadable("#000", ["#f00", "#0f0", "#00f"])->toHexString(); // "#00ff00"
\TinyColor\TinyColor::mostReadable("#123", ["#124", "#125"],['includeFallbackColors' => false])->toHexString(); // "#112255"
\TinyColor\TinyColor::mostReadable("#123", ["#124", "#125"],['includeFallbackColors' => true])->toHexString();  // "#ffffff"
\TinyColor\TinyColor::mostReadable("#ff0088", ["#2e0c3a"],['includeFallbackColors' => true,'level' => "AAA",'size' => "large"])->toHexString();   // "#2e0c3a",
\TinyColor\TinyColor::mostReadable("#ff0088", ["#2e0c3a"],['includeFallbackColors' => true,'level' => "AAA",'size' => "small"])->toHexString();   // "#000000",

Common operations

clone

clone: function() -> TinyColor\Color. Instantiate a new TinyColor object with the same color. Any changes to the new one won't affect the old one.

$color1 = tinycolor("#F00");
$color2 = $color1->clone();
$color2->setAlpha(.5);

$color1->toString(); // "#ff0000"
$color2->toString(); // "rgba(255, 0, 0, 0.5)"
