Colour is decided by the frequency of the electromagnetic wave ie light. There are cones and rods in our retina. The cones are sensitive to the frequency of the electromagnetic radiations falling on it. So colour is sensed by us. If there be any problem with those cones then colours cannot be differentiated. Such persons are called as colour blind people. Any way there is a limitation of sensing the frequencies. So right from red (lower freq) to violet (higher) are visible to our vision. Beyond these limits we cannot see.

Light colors are perceived by the human eye through specialized cells called cones in the retina. These cones are sensitive to red, green, and blue light, and the brain processes the signals from these cones to create the perception of different colors. The combination of these signals allows us to see a full spectrum of colors.

Why colored lights are called additive colors?

Colored lights are called additive colors because when different colored lights are combined, they add up to create new colors through the process of light mixing.
