I believe this is the most recent post on changing the MVP colors, so I'm bumping it. With the addition of the diamond rank, many people are noticing it is ridiculously similar to MVP. You can see an example of this in the image below. Zooming in, I think I can see a small difference in the shade, but it's still very frustrating. I think one of the colors, preferably diamond since it is more recent, should be changed have a noticeable difference. Right now, there is none.
If anything, it could just be riddled with a few diamonds on the rank, and have the color changed a bit. Granted, can't be too much or else people might complain that the individual looks like a moderator.
