Carl, there are some Irises out there I feel the same way about. Some of muted tones look dirty to me. I think that has more to do with my personal penchant for using a lot of bright, saturated colors, which make blooms with brown and beige look kind of dead. Although I have been working on a garden space with autumnal tones, so I'm starting to come around to liking some I had previously disliked.
