You can support us by [buying one of our paid products](https://spatie.be/open-source/support-us). We highly appreciate you sending us a postcard from your hometown, mentioning which of our package(s) you are using. You'll find our address on [our contact page](https://spatie.be/about-us). We publish all received postcards on [our virtual postcard wall](https://spatie.be/open-source/postcards). Installation ------------ [](#installation) You can install the package via composer: ``` composer require spatie/color ``` Usage ----- [](#usage) The `Color` package contains a separate class per color format, which each implement a `Color` interface. There are seven classes which implement the `Color` interface: - `CIELab` - `Cmyk` - `Hex` - `Hsb` - `Hsl` - `Hsla` - `Rgb` - `Rgba` - `Xyz` ### `interface Spatie\Color\Color` [](#interface-spatiecolorcolor) #### `fromString(): Color` [](#fromstring-color) Parses a color string and returns a `Color` implementation, depending on the format of the input string. ``` Named::fromString('blue'); Hex::fromString('#000000'); Rgba::fromString('rgba(255, 255, 255, 1)'); Hsla::fromString('hsla(360, 100%, 100%, 1)'); ``` Throws an `InvalidColorValue` exception if the string can't be parsed. > `Rgb`, `Rgba`, `Hsl` and `Hsla` strings are allowed to have spaces. `rgb(0,0,0)` is just as valid as `rgb(0, 0, 0)`. #### `red(): int|string` [](#red-intstring) Return the value of the `red` color channel. ``` Hex::fromString('#ff0000')->red(); // 'ff' Rgb::fromString('rgb(255, 0, 0)')->red(); // 255 ``` #### `green(): int|string` [](#green-intstring) Return the value of the `green` color channel. ``` Hex::fromString('#00ff00')->green(); // 'ff' Rgb::fromString('rgb(0, 255, 0)')->green(); // 255 ``` #### `blue(): int|string` [](#blue-intstring) Return the value of the `blue` color channel. ``` Hex::fromString('#0000ff')->blue(); // 'ff' Rgb::fromString('rgb(0, 0, 255)')->blue(); // 255 ``` #### `toCmyk(): Cmyk` [](#tocmyk-cmyk) Convert a color to a `Cmyk` color. ``` Rgb::fromString('rgb(0, 0, 255)')->toCmyk(); // `Cmyk` instance; 'cmyk(100,100,0,0)' ``` #### `toHex(): Hex` [](#tohex-hex) Convert a color to a `Hex` color. ``` Rgb::fromString('rgb(0, 0, 255)')->toHex(); // `Hex` instance; '#0000ff' ``` When coming from a color format that doesn't support opacity, it can be added by passing it to the `$alpha` parameter. #### `toHsb(): Hsb` [](#tohsb-hsb) Convert a color to a `Hsb` color. ``` Rgb::fromString('rgb(0, 0, 255)')->toHsb(); // `Hsl` instance; 'hsb(240, 100%, 100%)' ``` #### `toHsl(): Hsl` [](#tohsl-hsl) Convert a color to a `Hsl` color. ``` Rgb::fromString('rgb(0, 0, 255)')->toHsl(); // `Hsl` instance; 'hsl(240, 100%, 50%)' ``` When coming from a color format that supports opacity, the opacity will simply be omitted. ``` Rgba::fromString('rgba(0, 0, 255, .5)')->toHsl(); // `Hsl` instance; 'hsl(240, 100%, 50%)' ``` #### `toHsla(float $alpha = 1): Hsla` [](#tohslafloat-alpha--1-hsla) Convert a color to a `Hsla` color. ``` Rgb::fromString('rgb(0, 0, 255)')->toHsla(); // `Hsla` instance; 'hsla(240, 100%, 50%, 1.0)' ``` When coming from a color format that doesn't support opacity, it can be added by passing it to the `$alpha` parameter. ``` Rgb::fromString('rgb(0, 0, 255)')->toHsla(.5); // `Hsla` instance; 'hsla(240, 100%, 50%, 0.5)' ``` #### `toRgb(): Rgb` [](#torgb-rgb) Convert a color to an `Rgb` color. ``` Hex::fromString('#0000ff')->toRgb(); // `Rgb` instance; 'rgb(0, 0, 255)' ``` When coming from a color format that supports opacity, the opacity will simply be omitted. ``` Rgba::fromString('rgb(0, 0, 255, .5)')->toRgb(); // `Rgb` instance; 'rgb(0, 0, 255)' ``` #### `toRgba(float $alpha = 1): Rgba` [](#torgbafloat-alpha--1-rgba) Convert a color to a `Rgba` color. ``` Rgb::fromString('rgb(0, 0, 255)')->toRgba(); // `Rgba` instance; 'rgba(0, 0, 255, 1)' ``` When coming from a color format that doesn't support opacity, it can be added by passing it to the `$alpha` parameter. ``` Rgba::fromString('rgb(0, 0, 255)')->toRgba(.5); // `Rgba` instance; 'rgba(0, 0, 255, .5)' ``` #### `__toString(): string` [](#__tostring-string) Cast the color to a string. ``` (string) Rgb::fromString('rgb(0, 0, 255)'); // 'rgb(0,0,255)' (string) Rgba::fromString('rgb(0, 0, 255, .5)'); // 'rgb(0,0,255,0.5)' (string) Hex::fromString('#0000ff'); // '#0000ff' (string) Hsl::fromString('hsl(240, 100%, 50%)'); // 'hsl(240, 100%, 50%)' (string) Hsla::fromString('hsla(240, 100%, 50%, 1.0)'); // 'hsla(240, 100%, 50%, 1.0)' ``` ### `Factory::fromString(): Color` [](#factoryfromstring-color) With the `Factory` class, you can create a color instance from any string (it does an educated guess under the hood). If the string isn't a valid color string in any format, it throws an `InvalidColorValue` exception. ``` Factory::fromString('rgb(0, 0, 255)'); // `Rgb` instance Factory::fromString('blue'); // `Named` instance Factory::fromString('#0000ff'); // `Hex` instance Factory::fromString('hsl(240, 100%, 50%)'); // `Hsl` instance Factory::fromString('Hello world!'); // `InvalidColorValue` exception ``` Changelog --------- [](#changelog) Please see [CHANGELOG](CHANGELOG.md) for more information what has changed recently.
