Clay
A mid, warm orange with the energy of a warm sky.
Create Clay 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;
$clay = Color::parse('#B66A50');ColorInterface
$clay
#b66a50 · oklch(0.6032 0.1049 39.6)
Build a Clay harmony
tetradic() keeps Clay and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $clay->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#b66a50 - 1
#6d8d47 - 2
#178fac - 3
#946fb0
Generate a Clay scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $clay->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 Clay for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $clay->toHex();
$rgb = $clay->toCss('srgb');
$oklch = $clay->to('oklch')->toCss();- hex
#b66a50- rgb
rgb(182 106 80)- oklch
oklch(0.60325 0.104879 39.5657)
