+ ----------
89
+ gamma : float, optional, default: 1
90
+ Gamma factor emphasizing either low intensity values (gamma < 1), or
91
+ high intensity values (gamma > 1).
92
+ s : float, optional, default: 0.5 (purple)
93
+ The starting color.
94
+ r : float, optional, default: -1.5
95
+ The number of r, g, b rotations in color that are made from the start
96
+ to the end of the color scheme. The default of -1.5 corresponds to ->
97
+ B -> G -> R -> B.
98
+ h : float, optional, default: 1
99
+ The hue, i.e. how saturated the colors are. If this parameter is zero
100
+ then the color scheme is purely a greyscale.
