Thank you for the info guys. And even more thank you for the pictures.

Some gorgeous vandas you have!
Tucker, your Princess has much deeper blue color than mine, I like it better and probably eventually will add "Indigo Princess" to my collection too.
Ingse, I think I came across your photosteam on the net and saw White Princess Mikasa there. It seems her blooms have a bit of greenish color at the bottom. Is it true, or just a picture trick?
I see now that they all have some purple hint in them and Tuckers vasco is really the closest to blue I want.
I have V. Bangkok Blue seedling but it is years away from flowering.
I guess, I will have to wait for the show and hope there will be lots of blooming blue vandas to choose from

Thanks again!
