Additive color

Additive color is a type of color mixing we use to create colors that are seen on our devices like computers and phones. To mix colors with additive color, you start with a dark, black background. Then you use colored lights that are made of different colors like red, green, and blue. When all of the colored lights are turned on together, they mix together and create different colors. For example, when you put a red light, a green light and a blue light together, it creates a bright white light.
