Just wondering what color paste to use to color butter cream to imitate sand as I am making a birthday beach scene cake. I will be spreading gold colored sugar on the top but cannot find the right color for the butter cream undercoat.

I've used Americolor ivory.

I used Wilton brown with a touch of yellow.

lol brown and yellow = ivory. Or just buy ivory dye. I like the ivory dye and just make ir darker. What about using crushed nilla wafers, gram crackers, or cinnamon sugar for sand? You can sprinkle all that stuff on as well. I used gram cracker crumbs on one of the last cakes I made.
