DarkSlateBlue
A deep, warm violet with the energy of a warm sky.
Create DarkSlateBlue 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;
$darkslateblue = Color::parse('#483D8B');ColorInterface
$darkslateblue
#483d8b · oklch(0.4143 0.1248 286.0)
Build a DarkSlateBlue harmony
tetradic() keeps DarkSlateBlue and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $darkslateblue->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#483d8b - 1
#812634 - 2
#564e00 - 3
#005e62
Generate a DarkSlateBlue scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $darkslateblue->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 DarkSlateBlue for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $darkslateblue->toHex();
$rgb = $darkslateblue->toCss('srgb');
$oklch = $darkslateblue->to('oklch')->toCss();- hex
#483d8b- rgb
rgb(72 61 139)- oklch
oklch(0.414343 0.124836 286.039)
