You kidding? Train has a pathological, unreasoning hatred of the color blue and anything associated with it. He won't look at the sky in the daytime. He won't eat blueberries or look at the ocean. If he holds his breath too long, he turns purple. He thinks the primary colors are red, yellow, and green. He won't listen to the blues, he won't eat bleu cheese, he won't wear blue jeans...he avoids the color in all facets of his life. Even if blue isn't what he thinks it is, he'll still avoid it, because he can't face blueness.
