Personally I'm a big fan of Lava Lavender. I'm surprised I've not yet started a Lava Orchid project. In fact it looks like no one has probably done it yet, so even if someone beats you to it, you'll be one of few people producing it if you start now. I probably would next year if I didn't already have more important plans for my Orchid.
