Palettes countains at least 2 colors.

pub fn typ(&self) -> PaletteType

Says whether the palette is Sequential, Divergent or Qualitative.

pub fn blind(&self) -> Trivalent

Says whether the palette is colorblind safe (if the palette specifies it).

pub fn print(&self) -> Trivalent

Says whether the palette is suitable for desktop color printing.

pub fn photocopy(&self) -> Trivalent

Says whether the palette will withstand black and white photocopying.

pub fn lcd(&self) -> Trivalent

Says whether the palette is friendly for LCD screens (which tend to wash-out colors).

pub fn colors(&self) -> Vec<Color>

Returns the RGB colors of the palette.

pub fn gradient(&self) -> PaletteGradient<Color>

Returns a gradient constructed from the palette. It only makes sense for sequential and some diverging palettes.
