DarkOliveGreen
A deep lime with the freshness of a spring lime.
Create DarkOliveGreen 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;
$darkolivegreen = Color::parse('#556B2F');ColorInterface
$darkolivegreen
#556b2f · oklch(0.4955 0.0896 126.2)
Build a DarkOliveGreen harmony
tetradic() keeps DarkOliveGreen and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $darkolivegreen->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#556b2f - 1
#006e82 - 2
#6f548a - 3

Generate a DarkOliveGreen scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $darkolivegreen->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 DarkOliveGreen for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $darkolivegreen->toHex();
$rgb = $darkolivegreen->toCss('srgb');
$oklch = $darkolivegreen->to('oklch')->toCss();- hex
#556b2f- rgb
rgb(85 107 47)- oklch
