This so funny. You have the gray color that I plan to paint and you're thinking about going away from it.... I guess it is the old been-there-done-that.
I have been all over the charts thinking about color too. The problem, IMO, is these foxes don't just look great in any color. I was looking at "silver for a while, but I noticed that it appears to exaggerate all the panel seams, especially where the front bumper cover to fender meet; as does most other lighter colors.
One of your pics looks like an 87+ and not an 86; wondering if the grays on both are the same code?
Like another put it, maybe painting your moldings will freshin things up for you. I plan to paint mine on the 86GT vert. In addition I will body color the front widow framing. My son likes the black belt molding, but then he's only 17,
what does he know, lol. Probably the same things the original Ford molding designer did...
