Byzantine
A mid, warm magenta with the energy of a warm sky.
Create Byzantine 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;
$byzantine = Color::parse('#BD33A4');ColorInterface
$byzantine
#bd33a4 · oklch(0.5691 0.2096 336.4)
Build a Byzantine harmony
tetradic() keeps Byzantine and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $byzantine->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#bd33a4 - 1
#c45000 - 2
#00983c - 3
#0079e9
Generate a Byzantine scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $byzantine->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 Byzantine for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $byzantine->toHex();
$rgb = $byzantine->toCss('srgb');
$oklch = $byzantine->to('oklch')->toCss();- hex
#bd33a4- rgb
rgb(189 51 164)- oklch
oklch(0.569131 0.209641 336.366)
