I don't know about the colour cast; that tends to be vary from film to film. JD knows this kind of thing and could give you a better answer. You will generally find more contrast, which can result in blocked highlights or shadows. Remember, you're shooting transparencies, which do not have the same latitude as negative film. Also, you can expect more pronounced grain. Now, if these are things you are trying to avoid, it might take some trial and error to find a film that suits your purposes. I tend to consider these characteristics as features of this type of photography, and try to shoot to emphasize them when I can.
