Rust
A deep, warm orange with the energy of a warm sky.
Create Rust 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;
$rust = Color::parse('#B7410E');ColorInterface
$rust
#b7410e · oklch(0.5351 0.1625 39.5)
Build a Rust harmony
tetradic() keeps Rust and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $rust->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#b7410e - 1
#4d7e00 - 2
#007fad - 3
#894cb3
Generate a Rust scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $rust->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 Rust for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $rust->toHex();
$rgb = $rust->toCss('srgb');
$oklch = $rust->to('oklch')->toCss();- hex
#b7410e- rgb
rgb(183 65 14)- oklch
oklch(0.535099 0.162536 39.5073)
