Buttercup yellow is the yellow that has been through the entire color chart and returned to yellow as a deliberate conclusion: warm, specific, the color of a flower held under a child's chin. The Buttercup Yellow Chrysanthemum is 4.5 inches across, hangs on one screw, needs no water. The dense globe form in this color is the loudest object in any room it occupies. It has been the loudest object in rooms containing very loud things. It has not once found this embarrassing and we have stopped being surprised by this.
