Kelly Green
A mid green with the freshness of a spring green.
Create Kelly 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;
$kellyGreen = Color::parse('#4CBB17');ColorInterface
$kellyGreen
#4cbb17 · oklch(0.6999 0.2119 138.7)
Build a Kelly Green harmony
tetradic() keeps Kelly Green and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $kellyGreen->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#4cbb17 - 1
#00b1ff - 2

Generate a Kelly Green scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $kellyGreen->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 Kelly Green for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $kellyGreen->toHex();
$rgb = $kellyGreen->toCss('srgb');
$oklch = $kellyGreen->to('oklch')->toCss();- hex
#4cbb17- rgb
rgb(76 187 23)- oklch
