That really is a lovely color, Alice but if the orchid was treated, then when it re-blooms for you the flowers might be a different color. Yours at least looks like it probably is a genuine color.
Same as the Phals that are dyed blue. Most of them will re-bloom white. Just my opinion but I think if anyone wants an orchid that color they should just buy a fake one anyway. Then it will bloom all the time in the same color.
