Michael,

<quote author="Michael Schmid-3">

just read the documentation to get a few ideas what could be done:

Image>Color>Split Channels
Analyze>Histogram for each of the channels

or

Image>Type>HSB stack
Analyze>Histogram for each of the stack slices.
Especially the hue slice will be of interest to detect a change of  
hue (see http://en.wikipedia.org/wiki/HSV_color_space if you are not  
familiar with HSB)


I have tried what you mentioned, but both techniques seem to generate slices/channels with varying shades of black, gray, or white. This makes me think that the histogram will just generate its results based on brightness as opposed to RGB. Am I wrong?
