Some cameras have buttons for this i.e. indoors, outdoors etc. Try changing your camera's white balance for effect. Try using your indoor setting when filming sunsets etc.to make it even redder, and try using your outdoor setting indoors to create a blue clinical feel. When you add light to a scene you usually end up mixing light of different colour tempertures. To make light all of the same colour you have to fit gels over the lights.
Gels are plastic strips that attach via bulldog style clips to the light's barndoors.
Most of the time you will simply add a blue gel to a Redhead to give it daylight balanced light. We tried this out on one film, starting off with the Redhead bare, and increasing the number of orange gels, so that by the end of the film the light is almost red, turning a normal bedroom into a vision of hell. Light at Night Lighting at night is no fun at all. However much light you seem to pour onto a subject it still looks dark and grainy, either that or your subject looks blasted out - white and washed out, like a rabbit caught in a car's headlights. Day for night is a cheapo 60's style technique.
