Hi guys. I am in the market for a highway or freeway pastel. The reason I like the pastel better over the super pastel is because the yellow freeway or highway pattern when they are young is surrounded by black. Whereas in their super pastel counterpart, the yellow would be surrounded by gray. I wonder if that gray from a super pastel would darken as they age and turn a bit black. Because someone is making me an offer right now for a super pastel highway and I am really not liking the gray.
