Black
A dark, warm red with the energy of a warm sky.
Create Black 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;
$black = Color::parse('#000000');ColorInterface
$black
#000000 · oklch(0.0000 0.0000 0.0)
Generate a Black scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $black->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 Black for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $black->toHex();
$rgb = $black->toCss('srgb');
$oklch = $black->to('oklch')->toCss();- hex
#000000- rgb
rgb(0 0 0)- oklch
oklch(0 0 0)
