I have done enough CFL dimming to know that indoor ones used indoors do
not change color much from dimming. I have seen some get slightly warmer
or slightly cooler in color from change in current and change in
temperature, but that's it.

One complaint of dimming fluorescents is lack of the color getting
warmer as the lamps are dimmed. The lighting can take on a "dreary gray"
appearance with severe dimming as a result.

I expect you got a dud. The dimmable CFL I experimented with seemed to
work fine. It also performed a lot better after a day of full on burn in
period which I presume helped get all the mercury vaporized and the
phosphors settled.
