SlateBlue
A deep, warm violet with the energy of a warm sky.
Create SlateBlue 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;
$slateblue = Color::parse('#6A5ACD');ColorInterface
$slateblue
#6a5acd · oklch(0.5436 0.1712 285.5)
Build a SlateBlue harmony
tetradic() keeps SlateBlue and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $slateblue->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#6a5acd - 1
#be374d - 2
#7f7200 - 3
#008b8f
Generate a SlateBlue scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $slateblue->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 SlateBlue for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $slateblue->toHex();
$rgb = $slateblue->toCss('srgb');
$oklch = $slateblue->to('oklch')->toCss();- hex
#6a5acd- rgb
rgb(106 90 205)- oklch
