Granular sucrose, malic acid and cornstarch were colored with FD&C Yellow No. 5 and Blue No. 1. The pure and colored powders, each species having a different particle size, were mixed together in combinations where the colored ingredients in the mixture carried a different colorant and were subsequently sieved to retrieve the original carrier particles. The color of the retrieved powders indicated that the colorant particles were redistributed between the carrier's particles through migration and reabsorbtion.
