“Green Ukraine / Ukrainian Far East (1921, Russian Far East)”. FOTW "Flags Of The World". CRW Flags (2001年2月24日). 2018年10月24日閲覧。 “In “Flags of Non-Russian Peoples Under Soviet Rule” by Prof. Walter Trembicky [tbc69], pages 134 and 135, it mentions two proposed flags for Green Ukraine, or the Ukrainian Far East, neither of which was officially adopted, since the movement quickly proved abortive. There are simple black & white line drawings illustrating the two proposed flags on p. 133 of [tbc69]. The green in the two flags was described as dark or deep green. ... One [of the two proposed flags] was the Ukrainian blue-over-gold bicolor with a green triangle at the hoist.”
