IHC Image color deconvolution

[Cedric Espenel]

Hi Koundinya,

I'm not sure if that will answer your question but if you try:

from matplotlib.colors import LinearSegmentedColormap
cmap_Hema = LinearSegmentedColormap.from_list('mycmap', ['white', 'navy'])
cmap_DAB = LinearSegmentedColormap.from_list('mycmap', ['white', 
'saddlebrown'])
cmap_Eosin = LinearSegmentedColormap.from_list('mycmap', ['darkviolet', 
'white'])

You won't be able to get back to the original color but it will do a descent job:
