PowderBlue
A pastel, cool cyan -- the dependable foundation of trustworthy interfaces.
Create PowderBlue 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;
$powderblue = Color::parse('#B0E0E6');ColorInterface
$powderblue
#b0e0e6 · oklch(0.8751 0.0502 205.7)
Build a PowderBlue harmony
tetradic() keeps PowderBlue and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $powderblue->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#b0e0e6 - 1
#d8d0f4 - 2
#f6cac5 - 3
#d4dbb5
Generate a PowderBlue scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $powderblue->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 PowderBlue for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $powderblue->toHex();
$rgb = $powderblue->toCss('srgb');
$oklch = $powderblue->to('oklch')->toCss();- hex
#b0e0e6- rgb
rgb(176 224 230)- oklch
oklch(0.875083 0.0502041 205.731)
