I do something similar with my exterior lights - at sunset my lights come on at ~1% at 2000K. If they detect motion (in my driveway or back deck) they go up to 100% at 2700K. At sunrise they turn off.
Note that bulbs exist that automatically warm as they dim - so in my case the switches are smart, but the bulbs themselves are all dumb.
