Today is its first day of being open. If it continues to expand and/or the color deepens, I will take another picture. Thx for the info. I know a lot of orchids do that.
It is a seedling, possibly a selfing, of C. Eldorado concolor punctata. The lip must have reverted to wild tipe as far as the concolor was concerned, but in the center of the purple margin you can see a slight darkening, probably from the punctata characteristic. The main development since yesterday cannot be photographed. There is now a strong, spicy fragrance.
