Colormaps with certain characteristics.
val length : t -> intlength m returns the number of colors in the palette m.
val gradient : ?interpolate:bool -> t -> Gradient.tgradient m returns a gradient constructed from the palette. It only makes sense for sequential and some diverging palettes.
val ty : t -> [ `Seq | `Div | `Qual ]ty m says whether the palette is `Sequential, `Divergent or `Qualitative.
val blind : t -> [ `Yes | `No | `Maybe ]blind m says whether the palette m is colorblind safe.
val print : t -> [ `Yes | `No | `Maybe ]print m says whether the palette m is print friendly.
val copy : t -> [ `Yes | `No | `Maybe ]print m says whether the palette m is photocopy safe.
val lcd : t -> [ `Yes | `No | `Maybe ]print m says whether the palette m is friendly for LCD screens.

t listfind length return the list of palettes that support the desired properties and having at least length length. Note that most of the palette have ≤ 12 colors and the longer the palette, the less it will satisfy other properties. For properties selected with `Yes `No or `Maybe, setting `No (the default) means one does not care, setting `Maybe selects palettes that maybe (or for sure) satisfy the property and `Yes selects palettes that satisfy the property for sure.
ty, if provided, restricts maps to the color scheme:`Seq: Sequential scheme`Div: Diverging scheme`Qual: Qualitative scheme
blind: the palette should be safe for color blind people.print: the palette is print friendly.copy: the palette is photocopy friendly.lcd: the palette is LCD friendly.
val viridis : tMatplotlib colormaps
These are sequential colormaps (each with 256 colors). You can find more information on this page.
