If all else fails and you are patient, I am sure the next color in dyed orchids will be orange!
Orchids being what they are, the genetics in various genera dictate the colors available. Breeders continue to work hard to bring in colors that might be standard in some but unavailable in others. For Instance: orange Cyms are fairly common but not true orange in Phals; lavender is common in vandas but unavailable in Cyms; bright red is common to sophros and mini catts but unheard of so far in Cyms and vandas. I am sure other comparisons can be made.
