The color of these stamps varies wonderfully, every shade from pale to dark, with yellowish vermilion, pink, red, and carmine may be found. Some are undoubtedly changelings from accidental causes, particularly those that run from brown and black brown, to an almost jet black, which were at one time much sought after.
