Arctic
A pastel green with the freshness of a spring green.
Create Arctic 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;
$arctic = Color::parse('#C1E1C1');ColorInterface
$arctic
#c1e1c1 · oklch(0.8778 0.0551 145.1)
Build an Arctic harmony
tetradic() keeps Arctic and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $arctic->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#c1e1c1 - 1
#b5ddf6 - 2
#eacbeb - 3
#f4ceb5
Generate an Arctic scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $arctic->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 Arctic for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $arctic->toHex();
$rgb = $arctic->toCss('srgb');
$oklch = $arctic->to('oklch')->toCss();- hex
#c1e1c1- rgb
rgb(193 225 193)- oklch
