Dak,
Try and find a picture of a Self Blue Old English Game Bantam on the internet. That is what I believe the color is suppose to be as close as possible. Yes, the lighter shade is more eye appealing but as far as silvery(shiny) hackle and saddle feathers that will have to be determined when the standard is accepted. Try and stay away from the silvery feathers probably. The English I believe call the Lavender, \" Pearl grey\", so that would be closer to light color than dark if that is the case.
