The Osprey table of Cossack uniforms gives the trouser stripe, shoulder boards, cap band and cap crown as Crimson for Siberia and Yellow for Far East. However its the crown piping thats scarlet or yellow the cap crown itself is blue for all Cossacks. I had already painted four units with the wrong colours and the dliemma was whether I re-painted them all. Not a dilemma really, I knew my OCD would force me to re-paint them all.
