These are the main colors used in most cover ups. While alot of aspiring artist tend to use black over black and then do the cover up, try this little trick. Put the black in the areas that are the lightest and the very strong highly concentrated pigments of Infinity Pro over the darker areas that you are covering up. Reason being, it will balance out the colors and you will not have just some dark spot in the art work that is darker than the rest of the tattoo that screams ( COVER UP!!!!). I have covered older black pieces with greens, teals, and browns with little effort. Its all about the pigment load in every drop of Infinity, it totally saturates the skin and the area being covered and then you will open a whole new world of ideas that you can offer your clients and more possibility for their cover up needs.
