I have never seen any loss of colour with any Mapei grout....
the browns and the greys dont hold there colour there not course enough for floors, the recent superflex I agree takes a bit more mixing plus bal give you a 25 year guarantee
the thing with Ultracolour is, you have to use a mixer to mix it and not by hand. wait a minute or so then give another mix.
I've never mixed any grout with a mixer, Got one hellava wrist action though:smilewinkgrin:
