Shouldn't this be, "Let them eat brioche."?
Let Them Eat Cake displays a range of colors from blueberry to plum with a hint of pinkish-orange in the transition when used over black. It works well on its own or as a base for other colors.
Note: Let Them Eat Cake must be used over a black basecoat to see the shift effect. If used over white, it appears grey.
