Vermilion
A mid, warm orange with the energy of a warm sky.
Create Vermilion 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;
$vermilion = Color::parse('#E34234');ColorInterface
$vermilion
#e34234 · oklch(0.6129 0.2000 29.1)
Build a Vermilion harmony
tetradic() keeps Vermilion and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $vermilion->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#e34234 - 1
#799200 - 2
#009fc4 - 3
#975fe9
Generate a Vermilion scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $vermilion->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 Vermilion for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $vermilion->toHex();
$rgb = $vermilion->toCss('srgb');
$oklch = $vermilion->to('oklch')->toCss();- hex
#e34234- rgb
rgb(227 66 52)- oklch
