A:In short: No, not really. You should stick to a high contrast monochrome tattoo, the larger the better, so features are easier to recognize.
Google finds plenty of answers from professionals. Here are some quotes:
"Colors tend to get muted by dark skin tones. When you look at a tattoo, you are looking at the tattoo through the skin. Therefore, the darker the skin tone, the more muted the colors of a tattoo will appear. On coffee-colored complexions or lighter, colors can still be used although there are some limitations in the palette. On darker skin, certain consideration have to be made in choosing colors, though the tendency is to mainly use gray shading and solid black as solid black work will usually show on anybody." -- http://www.dreamlandcreations.net/myke/tattoos/tattoo_category_c=3.html
"The most important thing to understand is that the style should be adjusted for the design to be bold and show contrast well, especially if the person is very dark. In general I encourage having a large design tattooed on dark skin becauses it's easier to decipher the image. Believe me there's nothing more disheartening for a person with a new tattoo than to have all their friends wondering "what is that on your arm?" ....... Notice I phrased the question like I did. If your artist knows what he/she is doing they will take into consideration just how light or dark you are.If you are light caramel colored than you can have black & grey ,red,orange,blue & green. Moderate colored skin I use black & grey & red. Red combines with brown skin beautifully. Really dark skin I say you should stick to black and shades of grey." -- http://www.risingdragon.com/FAQ/FAQ.html
