STAFF PICK! Looking for a white to do highlights on top of watercolor, gouache and ink? In our tests of all our whites, the Dr PH Martin's Bleed-Proof White blew all the other whites out of the water! It is extremely opaque and formulated to stay white when applied over dyes or colors that tend to migrate up into the white after application and turn it dull. Will not chip or peel. For covering only, not for mixing.
