They've only been in the tank since last Tuesday. As far as my eyes can tell they look pretty much the same. I would have expected the color to begin to shift by now. As far as I know Dr. Mac grows his frags in a greenhouse then places them under 400 watt 20K XM's before shipping. I expect a pretty good shift in color under my 175 10K's. Since the lights have already turned off for the day I'll try to take some more pics tomorrow for comparison.
