Green
A deep green with the freshness of a spring green.
Create Green 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;
$green = Color::parse('#008000');ColorInterface
$green
#008000 · oklch(0.5198 0.1769 142.5)
Build a Green harmony
tetradic() keeps Green and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $green->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#008000 - 1
#0074bc - 2
#963ba3 - 3
#b23e00
Generate a Green scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $green->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 Green for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $green->toHex();
$rgb = $green->toCss('srgb');
$oklch = $green->to('oklch')->toCss();- hex
#008000- rgb
rgb(0 128 0)- oklch
