I think it was the bath temp.
I am sure it is 6061, I buy my bar from a reputable dealer, and it is labeled very well.
I have done blasted parts before, with good results, just not red.
I re-did the "pink" frame today, and the bath temp was a bit lower. (Cooler outside)
It held its color better, but I also used a different dye.
I used to steam my parts, but that led to streaking, the boiling gives me a much more consistent color.
Thanks for all your help guys, I really appreciate it.
