Gabor doesn't really do fashion highlights, so there aren't any colors really analogous to 12FS8 in this line. Your best bet is going to be something like GL11/25SS: Shaded Honey Pecan. Gabor colors are conservative by design, so that is about as close as you're going to get. Even here, the dark and light shades are blended up together and not really presented as highlights.
