No one would probably claim that Fuji Velvia is a film with exceptional true color. It adds a lot of saturation to the photo and makes them more expressive.
True color can be sometimes pretty boring.
See some great examples here. But adding saturation is tricky as it can introduce some nasty color shifts. This tool is not a universal cure but I would like to invite you to give it a try. Especially useful is the combination of gamma and saturation. Probably using the other controls might get you some interesting results too.
