Struct Hsl 

pub struct Hsl;

🌌 The HSL color space

The HSL color space is fairly widely used and convenient, but it is not based on sound color science. Among its flaws, colors with the same “lightness” value can have wildly varying perceptual lightness.

Its components are [H, S, L] with

• H - the hue angle in degrees, with red at 0, green at 120, and blue at 240.
• S - the saturation, where 0 is gray and 100 is maximally saturated.
• L - the lightness, where 0 is black and 100 is white.

This corresponds to the color space in CSS Color Module Level 4 § 7.
