GRAY WASH: DARK: Rather than mixing up a new batch each time you have to create some shading in a piece, Intenze created our Gray Wash Dark tattoo Ink with you in mind, so there is a consisent color for each time a tattoo calls for some shading. MEDIUM: Another tone created for shading your tattoos. Gray Wash Medium Tattoo Ink is slightly lighter than the dark Gray Wash. LIGHT: The lightest in our series of three specially developed grays to be used for shading. Intenze created this formula with you, our buyer, in mind, to keep things consistent. SUMI WASH: Specifically developed for tattoo shading, the Sumi Wash Tattoo ink joins our light, medium, and dark gray washes to give you diverse options when it comes to tattoo shading.
