Navy
A dark, cool indigo -- the dependable foundation of trustworthy interfaces.
Create Navy 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;
$navy = Color::parse('#000080');ColorInterface
$navy
#000080 · oklch(0.2711 0.1879 264.1)
Build a Navy harmony
tetradic() keeps Navy and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $navy->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#000080 - 1
#5f002d - 2
#4e0a00 - 3
#003d1f
Generate a Navy scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $navy->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 Navy for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $navy->toHex();
$rgb = $navy->toCss('srgb');
$oklch = $navy->to('oklch')->toCss();- hex
#000080- rgb
rgb(0 0 128)- oklch
oklch(0.27115 0.187888 264.052)
