F, D & C Powdered Dye (For use with powdered ingredients. Oil soluble)
This is FOOD GRADE dye. These can also be used in cosmetics or anywhere a powdered coloring agent needs to be used. You can start with anywhere from .01 - 3 percent of the total volume and work upwards; however, start with a small amount as these are very potent and not much will be needed, depending on the color desired. Colors can be mixed for limitless possibilities!
