What combination of colored lights will give you cyan?

Cyan is a secondary color created by combining two primary colors of light. In the additive color model, which is used for light, the primary colors are red, green, and blue.

To achieve cyan, you need to mix green and blue light. When these two colors are combined, they produce cyan by reflecting the green and blue wavelengths while absorbing red. This is because cyan light contains the wavelengths associated with both green and blue.

Red and blue light, on the other hand, would produce magenta. Red and green light creates yellow, while yellow and blue do not combine to form cyan in the context of additive color mixing. Therefore, mixing green and blue is the accurate combination to produce the color cyan.
