Enum Colormap 

pub enum Colormap {
    Turbo,
    Viridis,
    Coolwarm,
    Grayscale,
    Custom(Vec<(f32, [u8; 4])>),
}

A colormap from t in [0, 1] to RGBA8.

Variants

Turbo

Google’s Turbo rainbow (published table).

Viridis

Matplotlib’s perceptually uniform Viridis (polynomial fit).

Coolwarm

Moreland’s blue-white-red diverging map.

Grayscale

Linear black to white.

Custom(Vec<(f32, [u8; 4])>)

Colour stops (position, rgba): at least two, positions in [0, 1] and strictly increasing. Colours are interpolated linearly per channel and rounded; t before the first or after the last stop takes that stop’s colour.
