DarkGreen
A deep green with the freshness of a spring green.
Create DarkGreen 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;
$darkgreen = Color::parse('#006400');ColorInterface
$darkgreen
#006400 · oklch(0.4360 0.1484 142.5)
Build a DarkGreen harmony
tetradic() keeps DarkGreen and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $darkgreen->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#006400 - 1
#005b94 - 2
#762d80 - 3
#8c2f00
Generate a DarkGreen scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $darkgreen->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 DarkGreen for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $darkgreen->toHex();
$rgb = $darkgreen->toCss('srgb');
$oklch = $darkgreen->to('oklch')->toCss();- hex
#006400- rgb
rgb(0 100 0)- oklch
