Aqua
A pastel, cool teal -- the dependable foundation of trustworthy interfaces.
Create Aqua 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;
$aqua = Color::parse('#00FFFF');ColorInterface
$aqua
#00ffff · oklch(0.9054 0.1546 194.8)
Build an Aqua harmony
tetradic() keeps Aqua and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $aqua->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#00ffff - 1
#d5d0ff - 2
#ffb3bf - 3
#f0e55d
Generate an Aqua scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $aqua->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 Aqua for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $aqua->toHex();
$rgb = $aqua->toCss('srgb');
$oklch = $aqua->to('oklch')->toCss();- hex
#00ffff- rgb
rgb(0 255 255)- oklch
oklch(0.905399 0.15455 194.769)
