Actually Dot the two are about the same size. The 'G Fielder' (green dorsal) has a noticably narrower dorsal then the other. Which you can't really tell in this picture. The petals aren't as saturated in pink either which is probably do to the stronger green background this plant has.
Ah -- Ok. I can see that. Have you noticed that temperature has anything to do with the color?
That could be a factor. It's tough to know for sure in this case. The two bloomed fairly close (in time) together and our temps here have been constant. If it where summer vs. winter I would say "for sure"
I wondered because although I'm growing my Phrags in my warm basement greenhouse, when I bring them up into my more intermediate sunroom, the reds and pinks seem to be more intense, when the buds form and open in the sunroom.
