I couldn't find a specific example either, but blue seems to have been the predominant colour used by hombu(HQ) chutai, so it's plausible at least. 1chutai -red tails with white bolt, 2 and 3 chutai red and orange bolts respectively on green/camo tail. Yellow stars on all, although the hombu chutai used blue stars on a red bolt when they had Ki27's, so there's blue again.
