Additive color mixing occurs when different colors of light are combined to create new colors. This process is based on the principle that when light of different wavelengths overlaps, the resulting color is a combination of the original colors. The primary colors of light used in this method are red, green, and blue. When these colors are mixed in various combinations, they can produce a wide spectrum of colors. In additive color mixing, the more colors you add, the lighter the result becomes. For example, combining red and green light produces yellow, while mixing all three primary colors—red, green, and blue—results in white light. This technique is commonly used in digital screens, such as televisions and computer monitors, where pixels emit light to create images.
