They all received BR blue. (It was supposed to be a joke but obviosly failed!. Sorry.)
Someone at Swindon obviously had a misguided burst of enthusiasm for the new regime. AFAIK the Kings were the only class where all members received this livery.
The story goes that there was still some Caledonian paint in store at Polmadie and some Duchesses were repainted with it. Euston was apparently not impressed!
(I'm not sure of the veracity of this, as I understood the BR colour was Prussian blue*, which was also the Caledonian blue.
Riddles being ex LNWR managed to get its livery adopted for mixed traffic locomotives and well the Caledonian was LMS too, so....
Apparently the colour tended to fade (OK for Scottish rain, but no good for English sun? or was it just a rubbish modern synthetic pigment?)
* It's the colour I painted my blue Dublo Duchess and it looks right to me - I still have to do the lining....
That's the early experimental livery. The final colour chosen was lighter.
Apparently Sir Felix Pole said that he was glad to have gone blind as it meant he didn't have to see a blue King!
These are Jigsaws but contemporary - take the tender colour as the boilers seem darker because they're in shade.
It seems to be difficult to find colour photos showing the colour. I have a children's book somewhere with a blue Duchess (Atholl IIRC) on the cover, but again it's an artist's rendition. (A memory of my youth, but unfortunately a replacement copy! "What did you get that for?", said SWMBO - not an exact quote but along those lines....)
RMweb wins again and a King (post #9)
A thought on the jigsaws -The Scots were class 7P and shouldn't be blue. Nobody told Wrenn, but correct liveries weren't their strong point.
