Response to Chapter 4

This chapter was short but it made me fully appreciate just how amazing computers are, though they are no longer a new invention.  The idea of determining a precise color through three numbers is astonishing to me.  Also, the gamut shown on page 82 looks like an artwork itself.  I was also fascinated to learn about the layers of a digital photo, how a color photo is created by layering black and white/ monochromatic primary photos.  Cool stuff!
