What is the primary color that combines with blue to form cyan?

Cyan is a color that is formed by the combination of two primary colors in the additive color model. When blue combines with green, they create the color cyan. This is because blue and green light wavelengths are both part of the visible spectrum, and when mixed, they produce cyan.

In the context of color theory, primary colors like red, green, and blue (RGB) can be mixed in various combinations to create secondary colors. Cyan is a secondary color that emerges specifically from the combination of blue and green. This way of mixing colors is fundamental in light-based applications, such as screens and digital displays, where the additive color model is applied.
