A lot can be said with a limited amount of colors in a tattoo.  Many people choose to have what they call blackwork tattoos where the entire tattoo uses only one color.  The color black that is used for these blackwork tattoos is sometimes also used mainly for the outline of a tattoo, since the outlines need to be crisp and dark. Although there are a lot of tattoos out there filled with vibrant colors and rich detail, it is not always necessary to use so many colors in order to get the point of your tattoo across to it’s viewers.  With the proper shading, spacing, and use of lines and shapes, an intricately detailed tattoo, made with only black ink, can sometimes look even more spectacular than if it was made with three or four or even five colors.
