Nice work Jim - dad did one of these a while back finished in all over wasp stripes. I've certainly seen a picture of one at Round Oak in yellow, but I am unsure whether all over yellow would have been the 'as delivered' scheme which, going on the period of the rest of your stock, I guess is what you might want.
Those delivered to the United Steel Corporation (who owned YE Co) would have had some variation on the scheme seen on the 0-6-0 two thirds down the page here: Paxman History - Diesels for the World's Railways (1957)
The darker colour would have been maroon, with black and yellow stripes per this steam loco (also built by YE Co.):
Yorkshire Engine 2502 USC Exton Park Mines 1360 18 July 1964
I would be surprised if these yellow schemes much pre-dated 1960, certainly the catalogue shot here: File:Im1952EnV193-p4.jpg (of a slightly earlier type which I would imagine that you've seen) suggests a uniform, dark colour, probably green, as the similar locos used at Shotton seem to have been. Mike Edge would certainly have a better idea.
