The darker of your two Dutch is a color called Tortoise, which is showable. The lighter one is a Blue Tort, which is not a showable color.
Dutch is a marked breed (obviously) and 50% of the points are awarded based on markings. I can't see any DQ's (disqualifications) in the markings on the Tort, but it looks like there may be some faults that might cost you a few points.
