Can you get a GREY tattoo?
In this regard, can a black and GREY tattoo be colored in?
Black and gray tattoos don't hurt as much as color tattoos (in theory). The main reason for this is that with a color tattoo, you must apply pigment to every square inch of the skin. With black and gray, shading is achieved using less pigment than a color tattoo would require, so it is less painful.
Additionally, do gray tattoos fade?
Just like color tattoos, black and gray tattoos will also fade over time if you don't take great care of your body-art over the years. Again, like color tattoos, the components used in black ink have improved considerably over the last few years, helping to keep age-related fading away for longer.
Black and grey are the hardiest tattoo colours. They are dense and bold and their appearance lasts longer than colours. In contrast, the most vibrant colours such as hot pink, yellow, light green tend to fade faster. Darker colours, such as deep reds, are more fade resistant.
