Most of my White Queen Caladiums look like yours some days back, but after getting more sunlight they are showing more white and pink colors:

Izhar, Thanks for your response!
You may be right. This Green Caladium is growing in a field of White Queens--the others are the pure white variety--and all of them are in deep deep shade--double canopy of tall oak trees and then a canopy of azaleas.
Too bad! I really really like this version!
