How do Red, Green and Blue light combine into White light without needing the rest of the Visual Spectrum?

Question

As well, does combining Cyan, Magenta and Yellow light give you White light?

In: Physics

Answer 1

Mixing Cyan, Yellow and Magenta lights would give white light to your eyes. As someone else said your eyes are sensitive to red, green and blue.

Cyan is Green+Blue, Yellow is Red+Green, and Magenta is Red+Blue. So that’s 2 units of red, 2 of green, and 2 of blue. So it should appear white. Obviously we assume the light sources are of equal brightness, etc since we already do that for red,green,blue lights.
