Type:list of colors (default: [])

min

if not None, min is the minimal value of the domain

Type:float or None (default: None)

max

if not None, max is the maximal value of the domain

Type:float or None (default: None)

mid

if not None, mid is the value corresponding to the mid color.

Type:float or None (default: None)

scheme

Colorbrewer color scheme of the color scale.

Type:string (default: ‘RdYlGn’)

rtype

The range type of a color scale is ‘Color’. This should not be modifed.
