Flag was three horizontal bars of red over blue over white with a gold crown in the center.

Officers wore a Olive Drab or Field gray uniform based on Russian Officer uniforms of the era.

Enlisted Infantrymen: Artwork show an Olive Drab color but other narratives indicate a field-gray color. I prefer the Olive Drab option. The pants, coat, stockings, and cap were all the same olive drab color. The cap was a low pillbox (kilmarock style) with a rank/unit badge on the front. The shoes were black. The epaulets were in facings colors of infantry = scarlet, artillery = yellow, engineers = green, machinegunner = Light Blue.

Reserves and Irregular: They wore a traditional dress with the characteristic red pillbox cap. The artwork shows a man in mid-blue pants, multi-colored waist sash, heavily embroidered red vest and white stockings, shirt. Most of the clothing colors would vary between villages and clans.
