I personally like lights in the 2700-3000K range. Gives a nice warm glow similar to what you are familiar with incandescent bulbs. Anything beyond that and you start getting into the real blue light. We are doing our house now in Progress Lighting LEDs, which will fit a standard can. They are 725 lumens and provide plenty of light.

Hue bulbs can be adjusted for color temperature but I have moved away from them to use smart switches, which have a more normal usage pattern for my family and guests as opposed to using a phone or remote control switch.

Big question are you using smart dimmers and switches? Make sure you get good ones that are compatible with your bulbs. We are using Leviton Z wave dimmers and they work really well. Only on the rare occasion will you get a flicker.
