This further proves the pattern differences. If you look at the scales, it's almost as if they are surrounded by a line of yellow, because that shows the areas that have browned out over time.

Yes, it's a pastel. And I guess I have to say it's in my opinion, but I really am pretty sure on this one that it is in fact a pastel.
