How does color on a computer screen work? I always thought that color was a way that light reflects on different materials/objects. How does this work on a TV/computer screen?
In: Technology
Your eye has three color detectors and uses their relative output to determine color.
TVs take advantage of this by *only* emitting three wavelengths that exactly match those cells, and turning them up or down to make your brain interpret the signal as different colors.
