> That would be great. I just don't know where it would make the most sense to integrate this into MapProxy (code and configuration wise). Do you already have any ideas?
Yes, thats a good question. My first idea was to include it at the 
wms.py on the service level, because its somehow similar like the 
attribution, it gets applied on the fly at the end without changing the 
cache. But the problem is, that this will affect all layers, and not a 
specific one. The best would be, if the attribution could be moved to 
the layer level instead of service, so you can have different 
attributions for different layers. And at this point, the "grayscale" 
option would fit in best.
Do you think this could be possible?
