Because it's fading - it's a fugitive (non-permanent) pigment. If you accelerate the process with UV light, it will just fade sooner, and eventually disappear completely. Why would you want a non-permanent mark on something you considered artwork? Why not just use brown ink?

Like the other person said it is because the pigment is not lightfast. If you like the look of the brownish tone you are better off getting a professional brown pen or marker that is certified lightfast.
The other posibility is the paper you are using. If your paper isn't buffered or acid free it could be reacting wih the ink and causing it fade.
In eaither case this means the artwork isn't going to be permanant when exposed to UV light.

sun/light exposure... you can accelerate it putting the paper under a light bulb.
