These four images are all rendered spectrally.

Image subtractive-arith.jpg uses straightforward arithmetic averaging of 
4 colors.  Clearly, arithmetic averaging is not the way to simulate the 
mixing of pigments.

Images subtractive_blob-k.jpg and subtractive_blob-w.jpg use geometric 
averaging of 4 colors.

Image subtractive_blob-cmy.jpg uses geometric averaging of 3 colors.
