Peru
A mid, warm amber with the energy of a warm sky.
Create Peru 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;
$peru = Color::parse('#CD853F');ColorInterface
$peru
#cd853f · oklch(0.6782 0.1227 62.2)
Build a Peru harmony
tetradic() keeps Peru and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $peru->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#cd853f - 1
#56ad72 - 2
#49a0dd - 3
#c47ab9
Generate a Peru scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $peru->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 Peru for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $peru->toHex();
$rgb = $peru->toCss('srgb');
$oklch = $peru->to('oklch')->toCss();- hex
#cd853f- rgb
rgb(205 133 63)- oklch
oklch(0.678193 0.122749 62.1816)
