pretty sure shortly after gwen came out a-net made a statement about how they wouldnt fix clipping and/or dying ability of the blindfold.
in fact...
"Clipping issues Item has many known clipping issues. As of October 3, 2007, it was stated by Gaile Gray they will not be addressed by ArenaNet." (

i cant really find the update, but id assume if they dont change clipping they wont change dying.
/sign anyway, i have one on my mesmer with a mix of monument and elite lux dyed purpe+red and the blindfold is just a bit lighter hue of purple, bugs me a bit, but its still cute.
