OliveDrab
A mid lime with the freshness of a spring lime.
Create OliveDrab 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;
$olivedrab = Color::parse('#6B8E23');ColorInterface
$olivedrab
#6b8e23 · oklch(0.5995 0.1374 126.3)
Build an OliveDrab harmony
tetradic() keeps OliveDrab and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $olivedrab->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#6b8e23 - 1
#0092b4 - 2
#9568c0 - 3

Generate an OliveDrab scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $olivedrab->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 OliveDrab for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $olivedrab->toHex();
$rgb = $olivedrab->toCss('srgb');
$oklch = $olivedrab->to('oklch')->toCss();- hex
#6b8e23- rgb
rgb(107 142 35)- oklch
