I've seen these types of variations in a number of species. The
two most variable that I've worked with have been affinis and
wendtii. I have a variety of wendtii that I've grown for years
under a number of conditions. If I didn't _know_ that they were
all offsets from the same original group, I would not believe they
were the same plant.

My C. affinis was bright wine red beneath and dark forest green
above with lighter veins when I got it. When I tried to grow it
in a gravel/laterite substrate, both with and without supplemental
CO2 it didn't do well. It put out very few runners, and the color
turned to a washed out olive green.
Then I took what was left of the stand and moved it to my
paludarium with peat plates and laterite under the #1 gravel.
This tank has neither supplemental CO2 nor strong lighting (2 40W
bulbs over a 55G tank, but the water level is a good 10" below the
bulbs) Within weeks of moving to this set up, they had deepened to
a bright green on the top side, but the undersides have not
returned to their former brilliance... just pink toward the
petiole. This seems to be a small variety. The leaves are
slightly bullate, and only a few have slightly wavy edges. It
hasn't gotten large under any of the conditions it's been grown
under. Over the peat plates it has spread rapidly and now covers
a fair amount of the bottom of the tank.

Which issue was this? I couldn't find it.
