DarkRed
A deep, warm orange with the energy of a warm sky.
Create DarkRed 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;
$darkred = Color::parse('#8B0000');ColorInterface
$darkred
#8b0000 · oklch(0.3999 0.1641 29.2)
Build a DarkRed harmony
tetradic() keeps DarkRed and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $darkred->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#8b0000 - 1
#405100 - 2
#005a76 - 3
#572791
Generate a DarkRed scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $darkred->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 DarkRed for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $darkred->toHex();
$rgb = $darkred->toCss('srgb');
$oklch = $darkred->to('oklch')->toCss();- hex
#8b0000- rgb
rgb(139 0 0)- oklch
