Do you have to put water in the food coloring?

If you are using liquid food coloring, then yes, you will need to add water to it before using it. This is because liquid food coloring is very concentrated, and it can be difficult to mix it evenly into food without adding water.

If you are using gel food coloring, then you may not need to add water to it. Gel food coloring is thicker than liquid food coloring, and it can be easier to mix it evenly into food without adding water. However, if you find that the gel food coloring is too thick, you can add a small amount of water to it to make it easier to mix.

If you are using powdered food coloring, then you will definitely need to add water to it before using it. Powdered food coloring is very concentrated, and it can be difficult to dissolve it evenly into food without adding water.
