GhostWhite
A pastel, warm violet with the energy of a warm sky.
Create GhostWhite 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;
$ghostwhite = Color::parse('#F8F8FF');ColorInterface
$ghostwhite
#f8f8ff · oklch(0.9811 0.0093 286.2)
Tint GhostWhite for a system
GhostWhite is a neutral, so rotating its hue changes nothing. Design systems rarely ship a pure neutral either: give it a trace of chroma and it belongs to the palette around it.
<?php
$neutral = $ghostwhite->to('oklch');
foreach (['warm' => 60, 'fresh' => 150, 'cool' => 250] as $name => $hue) {
echo $neutral->withChannel('c', 0.02)->withChannel('h', $hue)->toHex().PHP_EOL;
}- Warm
#fff6ec - Fresh
#f0fdf2 - Cool
#effaff
Generate a GhostWhite scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $ghostwhite->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 GhostWhite for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $ghostwhite->toHex();
$rgb = $ghostwhite->toCss('srgb');
$oklch = $ghostwhite->to('oklch')->toCss();- hex
#f8f8ff- rgb
rgb(248 248 255)- oklch
