Marine
A mid, cool blue -- the dependable foundation of trustworthy interfaces.
Create Marine 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;
$marine = Color::parse('#0EA5E9');ColorInterface
$marine
#0ea5e9 · oklch(0.6847 0.1479 237.3)
Build a Marine harmony
tetradic() keeps Marine and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $marine->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#0ea5e9 - 1
#c976c8 - 2
#dc7f2b - 3
#51b261
Generate a Marine scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $marine->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 Marine for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $marine->toHex();
$rgb = $marine->toCss('srgb');
$oklch = $marine->to('oklch')->toCss();- hex
#0ea5e9- rgb
rgb(14 165 233)- oklch
oklch(0.684687 0.147869 237.323)
