matplotlib colors rgb

A module for converting numbers or color arguments to RGB or RGBA. The matplotlib.colors.rgb_to_hsv () function is used to convert float rgb in the range of 0 to 1 into a numpy array of hsv values. This module includes functions and classes for color specification conversions, and for mapping numbers to colors in a 1-D array of colors called a colormap.
