Struct Lch 

pub struct Lch;

🌌 The cylindrical version of the Lab color space.

Its components are [L, C, h] with

• L - the lightness as in Lab;
• C - the chromatic intensity, the natural lower bound of 0 being achromatic, usually not exceeding 160; and
• h - the hue angle in degrees.

See Oklch for a similar color space but with better hue linearity.
