GreenYellow
A pastel green with the freshness of a spring green.
Create GreenYellow 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;
$greenyellow = Color::parse('#ADFF2F');ColorInterface
$greenyellow
#adff2f · oklch(0.9130 0.2335 130.0)
Build a GreenYellow harmony
tetradic() keeps GreenYellow and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $greenyellow->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#adff2f - 1
#00ffff - 2
#ffafff - 3
#ffa15a
Generate a GreenYellow scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $greenyellow->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 GreenYellow for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $greenyellow->toHex();
$rgb = $greenyellow->toCss('srgb');
$oklch = $greenyellow->to('oklch')->toCss();- hex
#adff2f- rgb
rgb(173 255 47)- oklch
