Midnight
A dark, warm indigo with the energy of a warm sky.
Create Midnight 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;
$midnight = Color::parse('#1E1B4B');ColorInterface
$midnight
#1e1b4b · oklch(0.2573 0.0861 281.3)
Build a Midnight harmony
tetradic() keeps Midnight and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $midnight->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#1e1b4b - 1
#430a19 - 2
#2d2300 - 3
#002f2d
Generate a Midnight scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $midnight->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 Midnight for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $midnight->toHex();
$rgb = $midnight->toCss('srgb');
$oklch = $midnight->to('oklch')->toCss();- hex
#1e1b4b- rgb
rgb(30 27 75)- oklch
oklch(0.257333 0.086068 281.288)
