Hello Stein, I see, I'll give that a try. Thank you!

If you investigate bleaching you could also consider converting to a different colour space (HSV) where the S channel represents colour saturation. I guess this can work as a direct measurement of the degree of bleaching. So convert to HSV and do histograms of the three channels separately. Be aware that the H channel "Hue" is a circular representation of angle, so the endpoints might not suit your case. You can circumvent this by shifting the values 180 degrees.

Does anyone happen to know?
