For curious buyers, this is already more or less built in:
- Philips Hue + Hue Hub : the default Hue app can do this, leveraging Hue Labs "Feel better with light" that runs from the hub so you don't need a laptop or other device after the formula is installed.

- Apple HomeKit Adaptive Lighting + Hue or Eve -- I'm a big fan of Eve light strips. See more accessories here: https://www.imore.com/best-accessories-with-homekit-adaptive...
Beyond those, there are other options w/o getting too tricky:
- Hue + Hue Automations + LivingScenes (or similar) + shift at sundown/sunrise
- Hue Labs (various other options)
- Third party apps like HueDynamics, and f.lux itself

For what it's worth, the Philips Hue white bulbs that vary the white temperature are great, with a better fuller white than the full color bulbs.
