This colour has a red undertone, which can be used over and over for those rusty looking accents on metal pieces or where a solid brown with reddish undertone is needed. Rusty Brown is very strong in cover-ups. It likes to be mixed with white - when mixed with white, this colour will turn into a unique blend of brownish magenta. Rusty Brown is used by many Japanese tattoo artists to create accents in female kimonos.
