Bing, that isn't the way engineers think. Engineers don't see black or white, they simply analyze the crap out of everything no matter how simple and see the results and all their variations. Engineers see wavelengths below 390 nanometers (gamma rays, x-rays, and UV rays), the visual spectrum (390nm to 720nm), infrared waves, and radio waves (radar/TV/FM/AM). They see a spectrum from the total lack of any waves in the visual spectrum (black) to a total saturation of all the waves in the visual spectrum (white).
But it's nice to know that someone remembers that we exist.
