Marigold
A light yellow with the freshness of a spring yellow.
Create Marigold 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;
$marigold = Color::parse('#FBBF24');ColorInterface
$marigold
#fbbf24 · oklch(0.8369 0.1644 84.4)
Build a Marigold harmony
tetradic() keeps Marigold and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $marigold->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#fbbf24 - 1
#00ebc2 - 2
#93c6ff - 3

Generate a Marigold scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $marigold->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 Marigold for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $marigold->toHex();
$rgb = $marigold->toCss('srgb');
$oklch = $marigold->to('oklch')->toCss();- hex
#fbbf24- rgb
rgb(251 191 36)- oklch
