We now carry all 41 colors (more then what is shown in this picture) of AmeriColor food coloring. It is the preferred coloring used by many cake decorating people which is why I chose to make this my main coloring supply choice. I do carry some paste coloring along with LorAnn liquid colors (shown below) also more specialized powder and oil-based colors made for coloring chocolates.
Have you tried the Wilton Color Mist? They are great! I have all the available colors shown here.
Now carrying the Americolor liquid chocolate safe coloring. Now you can get the same great colors for your chocolates as your frostings.
