Espresso
A dark, warm amber with the energy of a warm sky.
Create Espresso 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;
$espresso = Color::parse('#3D2B1F');ColorInterface
$espresso
#3d2b1f · oklch(0.3068 0.0337 54.8)
Build an Espresso harmony
tetradic() keeps Espresso and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $espresso->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#3d2b1f - 1
#253425 - 2
#1e323e - 3
#382a39
Generate an Espresso scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $espresso->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 Espresso for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $espresso->toHex();
$rgb = $espresso->toCss('srgb');
$oklch = $espresso->to('oklch')->toCss();- hex
#3d2b1f- rgb
rgb(61 43 31)- oklch
oklch(0.306763 0.033736 54.7785)
