Welcome to Chromatacia a society set 500 years after the collapse of a society very similar to our own, whose very foundations are based on the rules laid down by Munsell the founder of Chromatacia. In this post apocalyptic future everyone (almost) follows the rules without questioning them, no matter how strange, absurd or illogical they seem to be. "The word of Munsell was the rules, & the rules were the word of Munsell. They regulated everything we did, & had brought peace to the collective for nearly 4 centuries. They were sometimes very odd indeed- banning of the number between 72 & 74 was a case in point, & no one had ever fully explained why it was forbidden to count sheep, make any new spoons or use acronyms. but they were the rules- & presumably for some very good reason, although what that might be was not entirely obvious."http://parrishlantern.blogspot.com/2010/08/shades-of-grey.html
