1. A lighting apparatus comprising:
- a first source of light;
a first surface for causing light transmitted therethrough from the first source to have a first color;
a second source of light;
a second surface for causing light transmitted therethrough from the second source to have a second color; and
coating means on said second surface to prevent light from the first source that is transmitted through the first surface from passing through the second surface.
