Elite Colors are FAT SOLUBLE and blend beautifully inside of chocolate! Keep in mind, however, that Elites are already activated and will take MORE powdered food coloring to achieve desired tones.
The general rule of thumb is 1/4-1/2 tsp per 4-6 oz of white chocolate. It will all depend how dark the color is that you are working with. Lighter tones, like Daisy, could take more. It is BEST to work with Elites on the accent colors of your treats, where you are attempting to color 6 oz of white chocolate or less.
Master Elites are not fat soluble and will not work to color chocolate, with the exception of Black and White Master Elites. These are the only two Master Elites that CAN tint chocolate.
