For the last 2 weeks, I have been using a Target brand food coloring brush. It seems like a lot of fun. It makes it easy to color food, but I honestly don’t see a noticeable difference in the colors once they are applied. My biggest concern is that the brush would get scratched and get dusty quite quickly.
Target says that it’s a water-based liquid color, which means that it’s not supposed to be washed away by water. So you would need to clean the brush regularly with water and perhaps a sponge. And you would also need to ensure that the water is replaced about every few hours.
