Were there any portable roundie colour TVs?

I suppose that to have a portable in those days there would have to have been a smaller tube than the standard 21"-maybe a 12" or so round tube. The 21" was just too big and bulky. There was enough trouble engineering a reliable 21" set, and they didn't sell all that great (at least at first) so its seems unlikely that anyone would put the money into designing a portable. But it would be pretty neat if they did!
