you can try washing it again in the hottest water you can to remove the retayne and then wash it again in the hottest water you can to try and fade it even further.
you can then over dye it yourself with purple to try and achieve a more uniform color.
with all that said i love the mottled look and wouldn't do a thing - but i'm not you and i understand the disappointment when a fabric doesn't turn out exactly as you wanted.
if you overdye with a dye like RIT, it will fade out every time you wash it. if you want it to stay as you dye it, you have to use a commercial (professional) dye. however, any dye you use will be mottled because it's starting out on mottled fabric.
it's very, very nice the way it is and definitely looks like it was supposed to be that way. i would wash it one more time to be sure it's finished doing whatever it did.
