Hi Joe:
I made no comment whatsoever regarding the paler shade of blue. When I stated "both of these are legit," it was with the knowledge that these Kokarden repose on real Braunschweiger helmets.
I've seen your I/II Bataillon up close and never doubted the authenticity of either the helmet or the Kokarde.
My sole criticism is that ultra glossy, no trace of age or wear, poor detail in the gold rings (or ring, if you prefer), not attached to a helmet, Kokarde you posted above is a modern reproduction and useless to any discussion of authentic color.
As for Ruhl, how faithful is a reprint of a graphic representation of something? When I look at the Sachsen-Weimar Kokarde, I see blue mixed in with the green (a printing registration error). Menzel? These are all drawings. I may be thick, but isn't an actual Kokarde more convincing than a comic book quality drawing?
Schwarzburg-Rudolstadt, blue with silver ring; Schwarzburg-Sondershausen, silver with blue ring. Yes, really. I must have missed a contradiction somewhere. I should clarify, for Mannschaften Kokarden, substitute blue and white (blue, white, blue) for Rudolstadt and white and blue (white, blue, white) for Sondershausen. Nowhere do I see blue/silver as the colors of Braunschweig.
It is a late night.
Chas.
