Are there any specific PHP libraries or extensions recommended for accurate RGB to HSL conversion in image processing applications?

Converting RGB to HSL values accurately is crucial in image processing applications to ensure correct color representation. One recommended PHP library for this task is "colormath-php," which provides functions for converting between different color spaces including RGB and HSL. 

// Install colormath-php library using Composer
composer require matthiasmullie/colormath

// Convert RGB to HSL using colormath-php library
use MatthiasMullie\Color\Color;

$rgb = new Color([255, 0, 0]); // RGB values
$hsl = $rgb->toHsl();

$hue = $hsl->hue;
$saturation = $hsl->saturation;
$lightness = $hsl->lightness;

echo "Hue: $hue, Saturation: $saturation, Lightness: $lightness";
