Sandstone
A light yellow with the freshness of a spring yellow.
Create Sandstone 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;
$sandstone = Color::parse('#C2B280');ColorInterface
$sandstone
#c2b280 · oklch(0.7650 0.0691 92.4)
Build a Sandstone harmony
tetradic() keeps Sandstone and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $sandstone->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#c2b280 - 1
#80c1b6 - 2
#a3b1df - 3

Generate a Sandstone scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $sandstone->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 Sandstone for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $sandstone->toHex();
$rgb = $sandstone->toCss('srgb');
$oklch = $sandstone->to('oklch')->toCss();- hex
#c2b280- rgb
rgb(194 178 128)- oklch
oklch(0.765006 0.069109 92.4296)
