SeaGreen
A mid green with the freshness of a spring green.
Create SeaGreen 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;
$seagreen = Color::parse('#2E8B57');ColorInterface
$seagreen
#2e8b57 · oklch(0.5685 0.1187 154.9)
Build a SeaGreen harmony
tetradic() keeps SeaGreen and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $seagreen->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#2e8b57 - 1
#2e7db8 - 2
#a15a93 - 3
#a66618
Generate a SeaGreen scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $seagreen->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 SeaGreen for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $seagreen->toHex();
$rgb = $seagreen->toCss('srgb');
$oklch = $seagreen->to('oklch')->toCss();- hex
#2e8b57- rgb
rgb(46 139 87)- oklch
