Sage
A pastel green with the freshness of a spring green.
Create Sage 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;
$sage = Color::parse('#86EFAC');ColorInterface
$sage
#86efac · oklch(0.8712 0.1363 154.4)
Build a Sage harmony
tetradic() keeps Sage and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $sage->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#86efac - 1
#81deff - 2
#ffb2f9 - 3
#ffc16f
Generate a Sage scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $sage->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 Sage for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $sage->toHex();
$rgb = $sage->toCss('srgb');
$oklch = $sage->to('oklch')->toCss();- hex
#86efac- rgb
rgb(134 239 172)- oklch
oklch(0.871163 0.136267 154.449)
