it could be, but in this case, i don't think so. i don't really have any good reason why, i just kinda have a feeling about.
i don't know if the flower will fade to white as it ages but i don't think so either.
I would not have suspected these pics showing flowers of one and the same plant :drool:!!! But IMO the actual blooms are great in shape in coloring!!! Jean
In most circumstances it is higher light levels which bring out an increase in anthocyanin display of flowers. Seldom do temperatures have that effect. Seeing the differences in your two photos is a good example of how this is observed.
Remember how you shade your green Cymbidium flowers in order to keep them so "clean" and the color so pure.
