FireBrick
A deep, warm orange with the energy of a warm sky.
Create FireBrick in PHP
Parse the catalog’s canonical value once, then keep the resulting color object throughout the rest of your code.
<?php
use PhpColor\Color\Color;
$firebrick = Color::parse('#B22222');ColorInterface
$firebrick
#b22222 · oklch(0.4968 0.1797 26.8)
Build a FireBrick harmony
tetradic() keeps FireBrick and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $firebrick->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#b22222 - 1
#5e6c00 - 2
#007a95 - 3
#7042ba
Generate a FireBrick scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $firebrick->to('oklch');
foreach ([0.97, 0.92, 0.84, 0.74, 0.66, 0.58, 0.48, 0.40, 0.32, 0.24, 0.16] as $lightness) {
$step = $oklch->withChannel('l', $lightness);

Format FireBrick for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $firebrick->toHex();
$rgb = $firebrick->toCss('srgb');
$oklch = $firebrick->to('oklch')->toCss();- hex
#b22222- rgb
rgb(178 34 34)- oklch
oklch(0.496771 0.179689 26.8148)
