Don't know what to tell you. Only thing I can think of is if you shorted something out. Check the copper trace on the back of the cluster and the fuses.
I have had mine installed for a month and have no issues. They look as red as can be as posted in my photos up above. I also did this on my brothers and he has had them for 2 weeks with no issues. They look just as red as mine. Don't know what LED's you used that caused yours to look pink.
