The blue Phalaenopsis (moth orchid) that you may be thinking of is an artificially colored plant. There is some work being done to create a true blue orchid by crossing certain plants, so who knows what colors they will come up with in the future. High-quality flowers are available in the entire color spectrum (except true blue in orchids). The closest to a blue orchid color would be the Vanda orchids but they are really more of a beautiful purple hue.
