I don't think the shades are different, I think the difference is in the lighting: natural light on Potts, and studio lights on the model. The stripes from teh armpit to the collar are different and there is no red piping on the pants.
I still say there is no way these are actual players, just models in teh uniform numbers of actual players.
If the red gets any lighter, it might just fade to pink. I actually like their previous uniform better. They took a definate step back on this one. It fits though, because that's kind of been their general direction though since they ditched Mike Leech.
