RebeccaPurple
A deep, warm violet with the energy of a warm sky.
Create RebeccaPurple 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;
$rebeccapurple = Color::parse('#663399');ColorInterface
$rebeccapurple
#663399 · oklch(0.4403 0.1603 303.4)
Build a RebeccaPurple harmony
tetradic() keeps RebeccaPurple and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $rebeccapurple->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#663399 - 1
#971e01 - 2
#425e00 - 3
#006587
Generate a RebeccaPurple scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $rebeccapurple->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 RebeccaPurple for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $rebeccapurple->toHex();
$rgb = $rebeccapurple->toCss('srgb');
$oklch = $rebeccapurple->to('oklch')->toCss();- hex
#663399- rgb
rgb(102 51 153)- oklch
oklch(0.440272 0.160296 303.373)
