Heh.
Actually, I really like Amethyst, 2100-424, but would probably recommend (none more) Black 2100-408 -- would go with anything!
But damn, that Iris shore is purdy! Good eye, thinking I'd like it.
Do you know, I even prefer the purple mouthwash. I just have to make sure not to confuse it with the purple window cleaner when I come home from shopping.
