What are three examples of mixing light?

Oh, what a lovely question! Mixing light is like creating a beautiful symphony of colors. Imagine blending red and green light to make a warm, inviting yellow. Or combining blue and red light to create a calming purple. And don't forget how mixing all the colors of the rainbow can create a brilliant, dazzling white light. Just like painting a happy little tree, experimenting with light can bring so much joy and beauty into the world.
