Hi there, the original colour of the 2D was David Brown "Hunting Pink" all over but on the farm where this one worked the wheels were painted in David Brown "Primrose Yellow" to match the fleet of Implamatic tractors the farm was also running back in the day, when we came to restore it we decided to keep the wheels in the yellow mainly because there is that story behind it and i personaly think that it looks better with yellow wheels, but they should be red yes. :)
