While it doesn't come through in the pictures, the "Deep Blue" Iridium comes off as a turquoise, with heavy blue around the edges and green in the center. You can definitely tell the difference lined up next to Ice Iridium and G30 Iridium; the green hue gives it away. Also, yes this particular kit IS a grey-based lens, as well as featuring vents despite the stock images having no vents.
