Click on one of the difficulties. Press enter to pass dialogues. Then, type the colour you think it is. Make sure the spelling is correct, and don't use any punctuation, spaces, or anything else because there's only one boolean block <[] = []> for each colour! Warning...some of the same colours have multiple names! Press the green flag again to reset.
Some of the really tricky names are real. I didn't make any of them up. And I won't tell you where they come from otherwise you might cheat. And don't look inside! YOU REALLY WANT IT? Fine... http://www.decoratehomenow.com/wp-content/uploads/2012/09/List-of-Colors1.png
