Cyber Wheel

A full hue rotation at constant lightness and chroma, so the wheel reads as pure color with no dead spots. The conic sweep makes it a natural color-picker backdrop or loading spinner.

Create Cyber Wheel in PHP

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

<?php

use PhpColor\Color\Gradient\Gradient;

$gradient = Gradient::conic(
    0,
)->stops(
    'oklch(0.60 0.30 300)',
    'oklch(0.60 0.30 200)',
    'oklch(0.60 0.30 100)',
    'oklch(0.60 0.30 300)',
)->build();
use PhpColor\Color\Gradient\Gradient; $gradient = Gradient::conic( 0, )->stops( 'oklch(0.60 0.30 300)', 'oklch(0.60 0.30 200)', 'oklch(0.60 0.30 100)', 'oklch(0.60 0.30 300)', )->build();

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 Cyber Wheel 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: conic-gradient(from 0deg, oklch(0.60 0.30 300), oklch(0.60 0.30 200), oklch(0.60 0.30 100), oklch(0.60 0.30 300));
background: conic-gradient(from 0deg, oklch(0.60 0.30 300), oklch(0.60 0.30 200), oklch(0.60 0.30 100), oklch(0.60 0.30 300));
