I have the German Battleship Bishmarck. To make it like it was in history I ordered the decals with the large swastika for the deck. It is just a white circle with the sastika inside it. I need to paint the red part of the flag before putting it on and I have no idea which red needs to be used since I’ve never painted one of those “flags” before.
Just as the Luftwaffe used RLM standard paints, the German navy used paints matched to the RAL standard. See if you can find out which particular RAL shade that they used. If no luck with that, then I suppose that the Luftwaffe RLM shade, the number escapes my foggy brain at this hour, would be a best guess substitute.
RLM 23 is Rot (red). IMO it is just a bit oranger than Insignia Red
Hint: many white decals are translucent when applied resulting,in your case, with a pink disc. Apply a similarly sized circle of white trim decal to the red area before applying the white & swaztika Decal.
I’d de-intensify [is that a word???] your color with a drop or two of grey or tan, for scale effect; even real fire engines don’t look that intense ‘fire engine red’ from any more than a chassis-length away.
I hope to use Vallejo but will use any acryic paint.
I wonder if Ammo Mig red 049 is too orange. It looks more red than number 6 in that chart. Of all the ones I have on hand that I’ve looked at that one look the closest.
