Probably opening up a can of worms but here goes.
About to start a Bf109/G5 night fighter and it calls for RLM76 all over. I have a bottle of Mil-Spec RLM76 and this is blue similar to RLM65, I also have a bottle of MRP RLM76 and this has a greenish tint to it. Humbrol 248 offering seems to have a greyish tint to it. Time frame for the aircraft is late 1943 to early 44.
Which shade would be most appropriate for the time?
