+XKCD.  He made a very curious experiment: showing colors to a lot of people
+and asking to name each one.  Afterward, he processed the data and sorted the
+names for each color by popularity --- that means, how many people gave the
+same name to the same color.  This package makes the collected color names
+usable with LaTeX.")
