Most people have forgotten the mysterious questions that a box of crayons presents to a kid such as: what am I supposed to do with this useless white crayon? why is the yellow crayon so dark and greenish, but draws such a pure, light yellow? is it just my eyes, or are the paper wrappers on the blue, indigo, and cerulean crayons the exact same color? I did not forget. These questions have been nagging me since kindergarten and this weekend I finally got to the bottom of it. I am now able to answer that age-old question: what really is the difference between green-yellow and yellow-green?
