50 Shades of Grey

This 8.5x11 in notebook consists of 50 sheets of major shades of grey (both sides of the same page have the same color and the corresponding RGB triplet is printed in the upper right corner on one side of each page). The notebook is a "print on demand" book by CreateSpace, and its main purpose is to help the authors considering CreateSpace as their publisher see how specific BW colors appear in the final printed books produced by CreateSpace (do light grey colors become pure white when they are printed? do dark grey colors become pure black?). Of course, this notebook can also be used for any other purpose where sheets colored in 50 shades of grey are useful (e.g. construction paper)... or it can be gifted to somebody as a joke.
