According to some food scientists, artificial food coloring is made with chemicals that have been shown to be dangerous to our health -- even in small amounts. Fortunately, natural food coloring alternatives are available, which let us infuse cupcake dough and frosting with a kick of vibrant color without sacrificing our well-being. Be aware that colors derived from vegetable-based dyes and other natural dyes generally aren't as intense as their chemical-rich counterparts. You may have to add more coloring or just live with a rosy blush rather than a true red, depending on the brand of dye you buy. Add one drop at a time to icing until you arrive at the color you want.
