Question

I need help. Please help me.?
There is a theatre. On that stage there were three lights - red, blue and yellow. Can you tell me how these lights might be uesd to create different lighting effects on the stage.

I just know red and blue will make magenta. We know blue and green light make cyan light. But here there is no green light, So blue can't make cyan light. And also when magenta and green overlaps, all three of the primary light colurs are present and we see white light. But here we will not be able to see white light because there is no green light.

Thats all I know. Just tell me if those are wirte. If you wanna share something, go ahead. It will be appriciated.

Answer 1

I do not know if lights work in the same way as primary colors but: Red-Yellow =orange
Red+Blue=Purple, Yellow and Blue= Green
Black is the absence of any color and white is all colors Don't know if it helps the best I can do. Oh yes I remember you can place colored film over the lights to do a color change.
