If someone who is able to use magic gets a tattoo, they are able to draw magic from it, but there are a few special conditions:
- They are permanently unable to use any magic that comes from the color that is the opposite of the tattoo. If they get two tattoos that are two opposing colors, those colors are permanently useless to them.
- The color does not drain from them ever.
- The energy available from the tattoo is considerably less than the energy they would have gotten from the same amount of color from a different source. Because of this, if someone gets a tattoo, they make it really big.
