Your orchid is indeed a Phalaenopsis! The purple color is from anthocyanin pigments. These pigments show up in these types of orchids with either pink, purplish or white flowers with purplish spots or bars.
The leaves, roots and stems all develop the color to some extent. However your orchid is close to death! You need to stop it from blooming!!! It is so wilted due to an immediate need to be repotted. You need to get it into fresh media so it can recover. By letting it keep on blooming, what little energy the plant has left, is going towards flowers NOT roots! You are literally letting it bloom itself to death!! That is not a good idea!
Misting it does no good at all, NONE whatsoever!
You need to look through all of our orchid "stickies" and " threads" that are found in our Orchid Forums. There are lots of posts there about repotting Phalaenopsis! But you need to remove the bloom spike, cut it ALL the way back and get it to make roots and leaves.
IF it is not too late, and I can not guarantee that it already is too late, you need to get it into new media. It may take a good 4-6 weeks to see roots grow. And then they can absorb water and plump those leaves back up. IF you do not repot soon, it will be too late and it won't tecover!
Condition critical!!
Good luck!
