Making cupcakes last weekend, I was surprised at just how challenging it was to tint the frosting the perfect shade. Granted, I was making rainbow cupcakes, so this task was multiplied by six, making the perfect red, orange, yellow, green, blue, and purple. Then a friend alerted me to a genius master guide to frosting colors published by Food Network Magazine. Check it out — you'll never be struggling over remedial color wheels again!The guide was published in their May, 2012 issue, but is still available online. It assumes you're starting with a basic box of red, blue, green, and yellow liquid food coloring, and then provides the ideal number of drops to achieve each color.
