Yeah, I went through a lot of soul searching on color temps for the new house. Most of the rooms have secondary recessed ("high-hat") lighting in addition to whatever the main lighting is for the room. This is the fashion in newer houses - and it's nice. LOT's of lighting if you need it. My old house feels like a dark cave now. This recessed lighting is ostensibly for use when cleaning the room, or working on something that requires a lot of light. I picked 4000K for all the recessed lighting (often called cool white).
The primary fixtures in all the bedrooms, baths, and main living spaces are 2700K (warm white, or traditional incandescent color).
There are areas, though, that get a lot more daylight exposure like the family room/kitchen/breakfast nook, so we decided to go all 4000K in there (except the kitchen counter which has low hanging 2700K lights). All under counter lights in the kitchen are 4K. Laundry room is all 5500K LEDs (bright white like fluorescent tubes, so you can see any spots on your clothes), as is the pantry closet.
Worked out nice. You get the warm 2700K lighting in most of the living areas, but if you need to clean the room, or wire up a TV, or assemble a piece of furniture, I can pop on the 4K high-hats.
For the chandeliers I went with 3000K LED fake-filament glass bulbs. They really look amazingly like real incandescent bulbs. I replaced all the tubular (music stand type bulbs) in our china cabinet with 3000K LED tubular glass bulbs.
There are so many LED options now, at reasonable prices, it just doesn't make any sense not to go that way.
I still have incandescent bulbs on one large chandelier, but that's because the dimmer it's on was adjusted improperly. Now that I've learned more about how LEDs work and how to adjust the dimmers for them, I'll eventually switch them out.
The only real down side to LEDs is their inability to dim down past around 40%. But I think the technology will continue to improve.
They even have LED replacements now, for fluorescent tubes.
