That one on the right in front seems to be a different brighter red than the others, in person that is. : ) I thought the others might be ox blood. I have blue on blue, green on green, as well as different colors on white, like brown, orange, blue, green. I think I can see some subtle differences in the swirls to. Some are more defined with other color shades, some are really swirled. I'm trying to study on the differences. Btw the collection comes from Pittsfield, MAINE.
