In my opinion it doesn't make much sense to use the RGB colors here
since they are arbitrary (well, ok, ideally "close" to natural colors).
What you can do:
- download the related CORINE shape file(s)
- extract training areas
- run i.gensigset to generate statistics
- run i.smap to do the classification
- validate
