Ember

A coal caught mid-burn: pale gold at the core falling to a deep orange edge. Radial and warm the whole way down.

Build a radial gradient from the catalog stops, then let PHPColor assign their positions.

<?php

use PhpColor\Color\Gradient\Gradient;

$gradient = Gradient::radial(
    'oklch(0.85 0.18 80)',
    'oklch(0.60 0.22 40)',
);

Each stop remains a color object, ready for conversion, contrast checks, or further manipulation.

<?php

foreach ($gradient->getStops() as $stop) {
    echo $stop->color->to('oklch')->toCss();
}

Serialize the gradient directly, or choose a wide-gamut notation for every stop.

<?php

$css = $gradient->toCss();
$p3  = $gradient->toCss('display-p3');

background: radial-gradient(circle at 30% 30%, oklch(0.85 0.18 80), oklch(0.60 0.22 40));
