The subject of color temperature is starting to drift.
2700k is about the average incandescent color temp you see with the typical household lamp. Color temperatures in an RV drift all over the place because you never have a constant supply voltage when on battery, or shore depending on what the charger is doing and supply voltage has a huge effect on color temp.. Either way, 2700k is the target for a homie look. The nice thing about LED's is that they never drift in temp due to voltage variations.
There are Warm White (WW), Cool White (CW), Daylight, and others that are just plain ugly. If you want a residential look, stick with the WW LED's. I went with the CW LED's that hover from 3000-4000k on the kitchen counter and in the microwave because it really makes colors pop. The only place I went cooler temps than that was in the exterior storage because I was after brightness over color accuracy, and the only way to get LED's into the warmer range is to dye the lens, and that causes the brightness to taper off.
