Deep Space

A dark radial gradient in indigo tones, interpolated in OKLCH across 3 stops so the ramp stays even from end to end.

Create Deep Space 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(0.30 0.14 280)',
    'oklch(0.20 0.10 270)',
    'oklch(0.12 0.05 260)',
);
use PhpColor\Color\Gradient\Gradient; $gradient = Gradient::radial( 'oklch(0.30 0.14 280)', 'oklch(0.20 0.10 270)', 'oklch(0.12 0.05 260)', );

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 Deep Space 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(ellipse at center, oklch(0.30 0.14 280), oklch(0.20 0.10 270), oklch(0.12 0.05 260));
background: radial-gradient(ellipse at center, oklch(0.30 0.14 280), oklch(0.20 0.10 270), oklch(0.12 0.05 260));
