Not as uncommon a color as you might expect Dot. The deeper orange-yellows are favored over the more lemony ones and much more than the pale ones. I love the long spurs on this one, making it look like a true, full-blood Neo. Some of the named varieties carry a silly price tag. I just bought this one as an unnamed Kibana (literally "yellow flower") and didn't have to empty the vault to get it.
Yubae is a very interesting orange-red form that is pricey indeed, but unique in its color and also has larger flowers - maybe there is something other than Ascocentrum in that one. I haven't spilled enough blood to buy that one yet though...
