Personally, I have colour-capable bulbs in my bedroom (paired with a smart switch). Using Adaptive lighting (https://github.com/basnijholt/adaptive-lighting) was a breeze to setup and offers more capabilities than I even need.
I can vouch for Adaptive Lighting. I use it in every room and it was very easy to set up.
It can be a bit tricky when working with scenes though – that's maybe the only downside I've come across.
