I did see you mention that in your original post. But you also said that isn't a sign of shedding. Color darkening and cloudy eyes are a sign of shedding in my opinion. :\
If she isn't limp, wheezing, popping, and is somewhat alert when you touch her (tongue flicking, flinching), then I personally wouldn't worry about it yet. If you're really worried, then take her to the vet.
I still think shed, however.
