Not all roses have one stable color. "The color" of this rose is evidently different at different times in different climates. This is not unusual with older roses at all - the tea roses are famous for having variable colors. I have one that is sometimes pale yellow, sometimes pale pink, and most of the time buff with a brick color on the back of the petals.

Cloud Nine is a modern hybrid tea, so one would assume that it would have ONE color, but from the pics on HMF it is a bit variable. If you really don't like the coral pink color, I would choose a different rose.

Thank you Jackie!
That was very helpful.
I'm going to choose L'aimant instead.
