Struct egui::Color32

pub struct Color32(_);

This format is used for space-efficient color representation (32 bits).

Instead of manipulating this directly it is often better to first convert it to either Rgba or Hsva.

Internally this uses 0-255 gamma space sRGBA color with premultiplied alpha. Alpha channel is in linear space.
