The most interesting part of the story came when he told me that after he mixed the paint color, sprayed a few test panels, and was approached by his boss. His boss asked what he intended to name the new color, to which he replied..."STATUTORY GRAPE!":wow: His boss then wryly asked him if he wanted to turn in his resignation that day or wait until tomorrow, insinuating that another name must be chosen...which lead to "Plum Crazy"
