getColor [#425]

def getColor(rgb=None, hsv=None):
 
docstring:
Convert a color or list of colors to (r,g,b) format from many
    different input formats.
​
:param bool: hsv: if set to `True`, rgb is assumed as (hue,
    saturation, value).
​
Example:
​
 - RGB= (255, 255, 255), corresponds to white
​
 - rgb= (1,1,1) is white
​
 - hex= #FFFF00 is yellow
​
 - string = 'white'
​
 - string = 'w' is white nickname
​
 - string = 'dr' is darkred
​
 - int=  7 picks color nr. 7 in a predefined color list
​
 - int= -7 picks color nr. 7 in a different predefined list
