Thanks so much for letting me know. I'm excited that it's an older piece of Fenton glass. As to the color, I actually own some colonial blue fenton, so I'm not sure why I was confusing the color of this one. It's really almost a periwinkle blue. I had searched through my copy of The Standard Encyclopedia of Opalescent Glass multiple times for this pattern, and somehow I managed to miss it! But there it is, right on page 154. They just refer to the color as "Blue". Again, thank you. Mystery solved!
