Our darker Stamping Gel Polishes have somewhat of a super power...add a little (or a lot) of white to them (just mix them right on your stamping plate!) and they create a one-of-a-kind color range! Need a lighter periwinkle blue? Add a dab of white to your plate along with Knot in the Navy and you'll get the prettiest periwinkle EVER! Or simply use as-is straight from the bottle for a bold, striking color!
