Grape
A deep, warm violet with the energy of a warm sky.
Create Grape 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;
$grape = Color::parse('#6F2DA8');ColorInterface
$grape
#6f2da8 · oklch(0.4553 0.1865 304.3)
Build a Grape harmony
tetradic() keeps Grape and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $grape->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#6f2da8 - 1
#a50800 - 2
#416500 - 3
#006a95
Generate a Grape scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $grape->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 Grape for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $grape->toHex();
$rgb = $grape->toCss('srgb');
$oklch = $grape->to('oklch')->toCss();- hex
#6f2da8- rgb
rgb(111 45 168)- oklch
