White chocolate's creamy color takes on tints for bright confections or edible decorations. The color can be anything from the palest pastel to the most vibrant hue, depending on how much food coloring you add. Use an oil-based food coloring when tinting white chocolate because water can make melted chocolate seize. White chocolate chips are a smart choice because they're easy to melt, but you can use any form of white chocolate as long as you melt it carefully.
Put white chocolate chips or pieces of white chocolate in a microwave-safe bowl and microwave for 1 minute. Stir the chips with a spoon.
Place the semi-melted chocolate chips back into the microwave and continue microwaving them for 10- to 20-second intervals, or until they are smooth and creamy. Stir the chips after each interval.
Add the oil-based food coloring to the melted chocolate, one drop at a time, until you reach the shade you want. Stir the chocolate thoroughly to evenly distribute the color.
