PerceptuallyUniformColormap.from_list

classmethod PerceptuallyUniformColormap.from_list(name, colors, ratios=None, **kwargs)

Make a PerceptuallyUniformColormap from a list of colors.

Parameters

• name (str) – The colormap name.

• colors (list of color-spec or (float, color-spec) tuples, optional) – If list of RGB[A] tuples or color strings, the colormap transitions evenly from colors[0] at the left-hand side to colors[-1] at the right-hand side.

  If list of (float, color-spec) tuples, the float values are the coordinate of each transition and must range from 0 to 1. This can be used to divide the colormap range unevenly.

• ratios (list of float, optional) – Relative extents of each color transition. Must have length len(colors) - 1. Larger numbers indicate a slower transition, smaller numbers indicate a faster transition.

  For example, red=(1, 0.5, 0) with ratios=(2, 1) results in a colormap with the transition from red 1 to 0.5 taking twice as long as the transition from red 0.5 to 0.

Other Parameters

**kwargs – Passed to PerceptuallyUniformColormap.

Returns

PerceptuallyUniformColormap – The colormap.
