Amber
A light, warm yellow with the energy of a warm sky.
Create Amber 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;
$amber = Color::parse('#F59E0B');ColorInterface
$amber
#f59e0b · oklch(0.7686 0.1647 70.1)
Build an Amber harmony
tetradic() keeps Amber and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $amber->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#f59e0b - 1
#29d38f - 2
#56b9ff - 3
#f786d4
Generate an Amber scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $amber->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 Amber for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $amber->toHex();
$rgb = $amber->toCss('srgb');
$oklch = $amber->to('oklch')->toCss();- hex
#f59e0b- rgb
rgb(245 158 11)- oklch
