With that wishbone shaped headstamp, it could be a Special. Do you know anything about the Pastel Special Pied's parents and if there is a chance it was mis-ID'd? I agree with Armiyana that it looks closer to a dark Mojave or even Mystic. The tones are a bit more abnormal from wild type, where Specials tend to have pretty close to wild type colors and the greater indication is in pattern.
