Lighting problems

What I’m trying to do is this:

I have two spheres, one red and one blue, and what I’d like to do is create a single light source that shines down on both. I have gotten that far. However, when I enable the lighting, both spheres become completely white.

How do I fix the lighting calls so that the spheres will retain their original colors? Thank you.

I was able to find my answer. Thanks for taking the time to read this.
