I am not a fan of orange, just because it's not my thing (subjective), so I would only order this for the purple and pink keys.
I imagine there are others like me, so here's something to keep in mind: the CMWY and CMWK sets produced in the past have a pink Ctrl key. If you put pink on Ctrl, thise people will essentially get another of the same key (provided the W/K legends match your choice). On the other hand. If you put pink on another colour, they can now have two pink keys if they want. Also, if Ctrl was purple, those people could now make a CPYW/K set by replacing their pink Ctrl if that suits their main alpha set better (again, provided that the W/K legends match).
Or you can just ignore all this and make a new set for new auidence, your call.
