Black & grey tattoos are done using only black ink, diluted with destilled water to create various shades of grey to achieve depth, realism, and texture without color. Known for its timeless, versatile, and often moody aesthetic. Popular for portraits, realistic scenes, or traditional designs. Artists achieve different tones by blending, stippling, or layering diluted ink, letting the skin show through for highlights, creating a photo-like effect for subjects like memorial portraits.
