OldLace
A pastel yellow with the freshness of a spring yellow.
Create OldLace 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;
$oldlace = Color::parse('#FDF5E6');ColorInterface
$oldlace
#fdf5e6 · oklch(0.9723 0.0216 83.3)
Tint OldLace for a system
OldLace 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 = $oldlace->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
#fff3e9 - Fresh
#edfaef - Cool
#ecf7ff
Generate an OldLace scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $oldlace->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 OldLace for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $oldlace->toHex();
$rgb = $oldlace->toCss('srgb');
$oklch = $oldlace->to('oklch')->toCss();- hex
#fdf5e6- rgb
rgb(253 245 230)- oklch
