Colors comparisons are always tricky using photos and computers. As for which one is more 'silvery', my opinion is just that...an opinion. The Meridian looks slightly brighter to me and the Crystal is more 'blue'.
I agree on the names...Just creative ways to apply labels to the color choices.
I can tell you that if you look at the two colors next to each other, they can be nearly identical....So close in fact, that I wouldn't be surprised if even the margin of error by the companies producing the colors is enough to make one come out looking almost exactly like the other and sometimes looking totally different from each other.
Evidence is in the link to the ultimate GTO site. Look at the Meridian Turquoise cars on that site. They are all over the place with no two exactly alike. Could be the cameras used, the paint manufacturer being different and all kinds of variances in light, shadow, etc.
