Red color (again)

["Daniel Larsson" <defdac at hotmail_com>]

I was wondering if this message:
http://fins.actwin.com/aquatic-plants/month.200201/msg00394.html
pretty much sums up the most recent knowledge on how to get red plants
display their red color?
It was hard to find any consistency in posts regarding getting really red
colors in red plants.

Is it true that red plants that have all nutrients available and is growing
very well actually turns green and this is a sign of good health, and to
get really red color you have to limit either P or N?
