Glacier
A mid, cool blue -- the dependable foundation of trustworthy interfaces.
Create Glacier 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;
$glacier = Color::parse('#72A0C1');ColorInterface
$glacier
#72a0c1 · oklch(0.6851 0.0696 240.2)
Build a Glacier harmony
tetradic() keeps Glacier and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $glacier->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#72a0c1 - 1
#b38bae - 2
#ba906e - 3
#7ba683
Generate a Glacier scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $glacier->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 Glacier for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $glacier->toHex();
$rgb = $glacier->toCss('srgb');
$oklch = $glacier->to('oklch')->toCss();- hex
#72a0c1- rgb
rgb(114 160 193)- oklch
