Dr. Land's 2 Wavelength Experiment:
After contacting the Editors at Scientific American re obtaining a reprint of the article about Dr. Land's Experiment, I found the article is no longer extent. As I did not have the 1968 article the Editors suggested as a "closest fit", Everything here is from my own memory and the drawings are my own.

3 Primary Color Theory:
The Drawing of the Rods & Cones was modified from the illustration on page 562 of

Illustrated by William A. Davis.

Munsell Color System:
All the illustrations were scanned in from page 532 of the Encyclopedia of Practical Photography listed above.  The Munsell Color Company, Inc of 10 East Franklin Street, Baltimore 2, Md. publishes the Munsell Color Book refered to in this subsection.

CIE Color System:
I scanned the CIE Chromacity Diagram on page 534 of the Encyclopedia of Practical Photography listed above.  After making the diagram smaller to fit my web pages, I had to erase all the diagram's lables and replace them with with more legible ones from my imaging software.  I used the first modified image to create the other chromacity diagrams with my own additional data.
