Question

Quizplus · Accepted Answer

Additive color mixing is used when lights of different colors are overlapped, as they add together to create new colors. This is commonly used in electronic devices such as televisions and computer screens. Subtractive color mixing, on the other hand, is used with physical substances such as paint or ink, where different colors of pigment are overlaid to create new colors by subtracting certain wavelengths of light. Opponent processes refer to the way that the human visual system processes color information, with opposing pairs of colors (such as red/green and blue/yellow) being perceived in a mutually exclusive manner. Saturation refers to the intensity or purity of a color.
