Which color results when only blue and green lights are mixed?

When blue and green lights are mixed, the resulting color is cyan. This phenomenon is based on the principles of additive color mixing, where different colors of light combine to form new colors. In the additive color model, blue and green are two of the primary colors. When they are combined, they effectively add their wavelengths together, producing cyan, which is a secondary color.

In contrast, magenta, yellow, and red are not formed by the mixture of blue and green light. Magenta is created by mixing red and blue light, yellow results from mixing red and green light, and red is a primary color that does not mix with blue and green to form any other color. Thus, mixing blue and green light leads specifically to cyan, affirming the correctness of the given answer.
