You can't make white food coloring, but you can get a commercially made icing whitener. It is used in cake icings when the butter in it causes the icing to be more of an off-white or pale yellow color. It can also be used to lighten the color of a cake icing if too much food color was used. It could also be used in other foods, as well, either cooked or uncooked foods. You can get it at many grocery stores, and also a stores that sell cake decorating supplies, such as Michael's. The one I use is made by Wilton.
