Thank you Stefan and Anne for such quick replies.
I am writing a gimp plugin, and if anybody is interested in how do that --

Hi,
I have this silly color filter that Stefan gave me:
def vanderwalt(image, f):
"""colorfilter, thanks to Stefan van der Walt"""

(image[...,BLU] > f*image[...,RED])
return bluemask
