Rose
A mid, warm red with the energy of a warm sky.
Create Rose 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;
$rose = Color::parse('#F43F5E');ColorInterface
$rose
#f43f5e · oklch(0.6450 0.2154 16.4)
Build a Rose harmony
tetradic() keeps Rose and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $rose->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#f43f5e - 1
#a19200 - 2
#00b0b9 - 3
#896fff
Generate a Rose scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $rose->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 Rose for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $rose->toHex();
$rgb = $rose->toCss('srgb');
$oklch = $rose->to('oklch')->toCss();- hex
#f43f5e- rgb
rgb(244 63 94)- oklch
