Create Emerald City in PHP

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

<?php

use PhpColor\Color\Gradient\Gradient;

$gradient = Gradient::radial(
    'oklch(0.88 0.18 150)',
    'oklch(0.45 0.25 160)',
    'oklch(0.18 0.12 170)',
);
use PhpColor\Color\Gradient\Gradient; $gradient = Gradient::radial( 'oklch(0.88 0.18 150)', 'oklch(0.45 0.25 160)', 'oklch(0.18 0.12 170)', );

Inspect and convert its stops

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

<?php

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

Format Emerald City for CSS

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

<?php

$css = $gradient->toCss();
$p3  = $gradient->toCss('display-p3');
$css = $gradient->toCss(); $p3 = $gradient->toCss('display-p3');
background: radial-gradient(circle at center, oklch(0.88 0.18 150), oklch(0.45 0.25 160), oklch(0.18 0.12 170));
background: radial-gradient(circle at center, oklch(0.88 0.18 150), oklch(0.45 0.25 160), oklch(0.18 0.12 170));
