Iris
A deep, warm indigo with the energy of a warm sky.
Create Iris 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;
$iris = Color::parse('#5D3FD3');ColorInterface
$iris
#5d3fd3 · oklch(0.4952 0.2137 284.8)
Build an Iris harmony
tetradic() keeps Iris and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $iris->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#5d3fd3 - 1
#bc0039 - 2
#786200 - 3
#008187
Generate an Iris scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $iris->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 Iris for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $iris->toHex();
$rgb = $iris->toCss('srgb');
$oklch = $iris->to('oklch')->toCss();- hex
#5d3fd3- rgb
rgb(93 63 211)- oklch
