purple: "a color circle based on spectral wavelengths will appear with red at one end of the spectrum and violet at the other, and with a wedge-shaped gap representing colors which have no unique spectral frequency; these extra-spectral colors, the purples, are rather formed by the additive mixture of colors from the two ends of the spectrum."
violet: "because i want … to. i've wanted to ever since i saw you that day in the elevator. i know you don't believe me, but i can prove it to you. you can't believe what you see. but you can believe … what you feel. i've been thinking about you all day." (bound, 1996)
