Creating color

Hex

Lowercase, uppercase, with/without hash:

Color::fromHex('#0f4c81');
Color::fromHex('#0F4C81');
Color::fromHex('0f4c81');
Color::fromHex('0F4C81');

RGB

Integers, floats, indexed or associative array of integers/floats:

Color::fromRgb(15, 76, 129);
Color::fromRgb([15, 76, 129]); 
Color::fromRgb([
    'r' => 15,
    'g' => 76,
    'b' => 129,
]);

Color::fromRgb(0.06, 0.3, 0.51);
Color::fromRgb([0.06, 0.3, 0.51]);
Color::fromRgb([
    'r' => 0.06,
    'g' => 0.3,
    'b' => 0.51,
]);

HSL

Integers, floats, indexed or associative array of integers/floats:

Color::fromHsl(208, 79, 28);
Color::fromHsl([208, 79, 28]); 
Color::fromHsl([
    'h' => 208,
    's' => 79,
    'l' => 28,
]);

Color::fromHsl(0.58, 0.79, 0.28);
Color::fromHsl([0.58, 0.79, 0.28]); 
Color::fromHsl([
    'h' => 208,
    's' => 79,
    'l' => 28,
]);

Color::fromHsl([208, 0.79, 0.28]); 

HSV

Integers, floats, indexed or associative array of integers/floats:

Color::fromHsv(208, 88, 51);
Color::fromHsv([208, 88, 51]); 
Color::fromHsv([
    'h' => 208,
    's' => 88,
    'v' => 51,
]);

Color::fromHsv(0.58, 0.88, 0.51);
Color::fromHsv([0.58, 0.88, 0.51]); 
Color::fromHsv([
    'h' => 0.58,
    's' => 0.88,
    'v' => 0.51,
]);

Color::fromHsv(208, 0.88, 0.51);

CMYK

Integers, floats, indexed or associative array of integers/floats:

Color::fromCmyk(88, 41, 0, 49);
Color::fromCmyk([88, 41, 0, 49]); 
Color::fromCmyk([
    'c' => 88,
    'm' => 41,
    'y' => 0,
    'k' => 49,
]);

Color::fromCmyk(0.88, 0.41, 0, 0.49);
Color::fromCmyk([0.88, 0.41, 0, 0.49]); 
Color::fromCmyk([
    'c' => 0.88,
    'm' => 0.41,
    'y' => 0,
    'k' => 0.49,
]);

Random

Generate random color:

Color::random();

Just echo it

You can use a Color object as string:

echo Color::fromHex('#0f4c81');

Color manipulations

$color->rotate(120);
$color->complementary();

Useful Information

E.g. to decide which font color to use with given background color you can detect whether the color is bright or dark:

$color->isBright();
$color->isDark();

Distance of RGB values for two given colors:

$color->distanceRgb($anotherColor);
