Use colorblind friendly cudtools as colormap

cudtools_colormap.py

import numpy as np
import matplotlib.pyplot as plt

# use the colorblind friendly colors
# https://code.google.com/p/python-cudtools/source/browse/cudtools.py
import cudtools

numlines = 20


# normal use:
colorgen = cudtools.CUDcolorGen() 
for i in range(numlines):
    c = next(colorgen)
    print c

# create a colormap function for cudtools
cudcmap = lambda x: cudtools.CUDcolorD[cudtools.CUDcolorOrderL[x%cudtools.LL]]
