Coloured buns seems to be a hot trend right now, but has McDonald’s China gone too far with its new grey burger bun? The Modern China Burger, available until early November, consists of a slow-cooked pork patty, bacon, lettuce, pepper ketchup, and a speckled bun stained with sesame.

Promotional pictures and TV commercials put the bun in a light that gives it a glimmer/metallic grey look but the real life version looks slightly more anemic.
