Slide film is quirky. It's not as forgiving as color negative film, which means the exposure has to be right on the money. It's also very sensitive to different types of lighting, so using the wrong kind can result in strange colors. During manufacture the film is balanced for daylight scenes or for those lit by tungsten light sources. Daylight balanced film should be used when photographing outdoors or when using a flash.
Tungsten film is produced for scenes illuminated by a heated tungsten filament.
That means a conventional light bulb. Tungsten light sources do not include fluorescent lights. Fluorescent lights have their own wacky set of circumstances. In most residency situations, tungsten balanced film is not practical. It's not fast enough to photograph indoors without a tripod.
