Don't turn my orchid blue

I got a Cattleya orchid from the nursery, and I've become rather obsessed with it. Probably because I haven't managed to kill it yet. In fact, it seems to be flourishing and has new buds coming in. I've been diligently watering and fertilizing it, and making sure that it gets enough sun (but not too much sun), and that the temperature is just right. And when I run my dishwasher, I sit it on the counter so it can bathe in the the warm humid air. Like I said, slightly obsessed. Behold my orchid in all its glory!
