" On canvas with paint In the Artist’s school It’s red that is hot And blue that is cool. But in science we show As the heat gets higher That a star will glow red Like the coals of a fire. Raise the heat some more And what is in sight? It’s no longer red It has turned bright white. Yet the hottest of all, Merlin says unto you, Is neither white nor red When the star has turned blue. "

― Neil deGrasse Tyson , Merlin's Tour of the Universe
