Current colors are red, yellow, light blue, and dark blue, and the bears have a square imprinted below the hands that says, "180 ccm, 6.0 fl oz". I have another bear that is dark brown that does not have that imprinting or the black drawn on the mouth and eyes, but is otherwise identical; I'm assuming it is an older version. A reader, Heidi McGuire, recalled that in the '60s, she had one that had a flocked finish and was a deep mustard/honey color. Sounds fantastic!

If you know of any other colors, I would love to hear about them.
