I think if your seeing purple, your monitor is way off.
There might be a slight magenta cast in it due to the reddy bracken and reddy brown of the tree's, but purple, definately no.
I have, and do profile my monitor every couple of weeks with a Color Munkey, its as accurate as I know, all prints I send off come back matching the screen and look perfect re exposure and colour values.
I know its off topic, but how many of you guys profile regularly, as well as print profile?
Ive just printed an A4 print just to check color, and it seems to match ok this end.
I know there is a slight magenta cast in the reds, but its not as bad as you've mentioned.
From your reply you sound as someone who should get their kit profiled, especially if you want to print from. Beleive me, when I first started in digital I would get my prints back with so much difference it was unbeleivable. When I started calibrating my monitor, it made a big difference. When I calibrated my printing too, it made so much sense as well as saving money in the end.
