The pink is so light and quite beautiful. But I thought to be a true "concolor" it had to be ALL the same color, including the lip and throat.

Don, it may not be apparent in the photo, but the lip has the same color the petals and sepals have. The yellow in the throat in concolor, caerulea, alba, amethystina etc are acceptable, in fact it is normal the presence of certain amount of yellow.
