Struct nannou::color::RgbHue

#[repr(C)]
pub struct RgbHue<T = f32>(/* private fields */)
where
    T: Float;

A hue type for the RGB family of color spaces.

It’s measured in degrees and uses the three additive primaries red, green and blue.

The hue is a circular type, where 0 and 360 is the same, and it’s normalized to (-180, 180] when it’s converted to a linear number (like f32). This makes many calculations easier, but may also have some surprising effects if it’s expected to act as a linear number.
