Brick
A mid, warm red with the energy of a warm sky.
Create Brick 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;
$brick = Color::parse('#CB4154');ColorInterface
$brick
#cb4154 · oklch(0.5769 0.1735 16.6)
Build a Brick harmony
tetradic() keeps Brick and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $brick->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#cb4154 - 1
#887d00 - 2
#00959c - 3
#7563d9
Generate a Brick scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $brick->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 Brick for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $brick->toHex();
$rgb = $brick->toCss('srgb');
$oklch = $brick->to('oklch')->toCss();- hex
#cb4154- rgb
rgb(203 65 84)- oklch
oklch(0.576905 0.173502 16.6133)
