I like to use powdered food coloring better than paste food coloring because if the paste bottles lay on their side, they tend to seep out and color their storage container. In addition, the powdered food coloring is more versatile because you can use powdered food coloring with candy as well and paste colors do not work to color chocolate candy. I never use liquid food colors like you would buy in a supermarket because they tend to make the icing too watery.
