OrangeRed
A mid, warm orange with the energy of a warm sky.
Create OrangeRed 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;
$orangered = Color::parse('#FF4500');ColorInterface
$orangered
#ff4500 · oklch(0.6602 0.2294 35.4)
Build an OrangeRed harmony
tetradic() keeps OrangeRed and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $orangered->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#ff4500 - 1
#71a700 - 2
#00aee9 - 3
#b560ff
Generate an OrangeRed scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $orangered->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 OrangeRed for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $orangered->toHex();
$rgb = $orangered->toCss('srgb');
$oklch = $orangered->to('oklch')->toCss();- hex
#ff4500- rgb
rgb(255 69 0)- oklch
