@pby5a Two more fantastic paint schemes! I especially like the Royal Navy one =)
Your Galer paint scheme looks grey to me. I sadly couldn’t find the rgb code for it, but I found those references from model paints:
(Mr Paint M-485 until 1942 - later MRP-133)
Mind you, I’m not sure if my reference color is correct. It still looks a bit dark to me,
definitely darker than the colors in my post above. Hopefully someone who is more knowledgeable about WWII colors than I can chime in 
Sorry if I caused confusion!
