What are the primary colors used in the additive color model?

The primary colors used in the additive color model are red, green, and blue. This model is based on the principle of adding light together to create a wide spectrum of colors. In additive color mixing, different colors of light are combined to produce new colors; for instance, when red and green light are mixed, they produce yellow, and combining all three – red, green, and blue – creates white light. This model is particularly significant in fields such as digital imaging and electronic displays, where light is the medium used to represent colors.

The other selections do not represent the additive model. Yellow and blue, for instance, are part of the subtractive color model, which is used in processes like printing where colors are created by subtracting varying wavelengths from white light reflecting off a surface, making those options unsuitable for the additive context.
