Dyeeee. =]
Try dyeing them colors, if you don't want to dye/damage/don't think you'll get the right color you can make them. All it takes is artificial hair and (the dye of choice) and all the stuff you used to make the your dreads. There are a lot of videos on youtube explaining that a bit better than I can.
Add hemp to then- like get a friend who knows how to do that over a dread, or some small loose hairs.
Or beads.
Or if you're looking for something simpler then maybe just pull them back with a hair tie. (that ones really boring D:)
