Coral
A light, warm red with the energy of a warm sky.
Create Coral 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;
$coral = Color::parse('#FB7185');ColorInterface
$coral
#fb7185 · oklch(0.7192 0.1690 13.4)
Build a Coral harmony
tetradic() keeps Coral and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $coral->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#fb7185 - 1
#b8a700 - 2
#00c3c2 - 3
#9893ff
Generate a Coral scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $coral->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 Coral for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $coral->toHex();
$rgb = $coral->toCss('srgb');
$oklch = $coral->to('oklch')->toCss();- hex
#fb7185- rgb
rgb(251 113 133)- oklch
