Full Question: When dealing with colors, I often think in terms of three primary colors being mixed on a color wheel. However, I know that the colors my eyes see are actually light waves of different frequencies that can be represented on a color spectrum. For this reason, I like to visualize the ends of the spectrum connected to form a wheel. But, if the color wheel comes from the looping of a spectrum rather than the mixing of colors, where does purple come from? Why should mixing red and blue light create light with a higher frequency than either color, when mixing red and yellow light or blue and yellow light creates a color with a frequency somewhere between the two colors?
