Hi, Battle of Britain 1940 saw the use of the bright red and bright blue, clealry evident in many colour photos from then (not those coloured up things...hate !) the duller red oxide ish red and the darker less saturated blue came in and was widespread a bit later on. I dont see model paint makers making the early war colours much. Colourcoats have BS105 oxford Blue and BS381c 110 RAF Roundel Blue, though looking at both these clours on google sees a myriad of blues, internet useless at portraying anything as such, actually the image posters are at fault. as the screen can only display the RGB its given.
I may be right in saying Oxford Blue is the earlier blue, anyone care to chip in ? Wish I knew what red they sell for the early roundels. they sell BS538 and I see Xtracolor have that as post office red but those darn colour squares in google images have it looking more like the later war red oxideish colour. Sovereign Hobbies need to say which red it is for.
Rear of the book British Aviation Colours of World War Two , RAF Museum Series Volume 3 1976 colour paint chart (paint not print) which is THE BOOK BAR NONE) has names Matt Red and Matt Blue and the colours look like I would expect. I hope Jamie at Colourcoats has matched to those.
That aside, your yellow spoon looks canaty yellow, RAF Trainer Yellow is in that book, and that is the only accurate yellow, its not the BS381c 356 folk mention, there is NO colour ref except that book. beware model paint makers match to the BS381C 356 and its wrong. They cant be bothered to get hold of that chart. I compare Bs381C 356 to my 1976 book and the yellows ARE DIFFERENT. Peter Vacher's book on the Hurricane said so in the back as well.
Don't assume decals are right , wrong reference to match to if wanting to get colours as they really were.
