There are other ways of punching up contrast and saturation, with filtration, lighting, film emulsion, or even modifying C-41/E-6 chemicals. You can make the developer more or less contrasty to a limited extent. Also, you can push process easily if you're doing your own processing (labs make pathetic excuses as to why they won't/can't). Just as with B&W, contrast and grain goes up, while tonal scale is decreased. Hope this helps.
