As it turns out, as brightness decreases, the range of color temperatures that the eye will perceive as “white” narrows substantially. If the lighting is as bright or brighter than a well lit office, then you can get away with a wide range of color temperatures which the eye will perceive as white, at least after adaptation. But once you get to a significantly dimmer living room at night, you’ll need much warmer lighting to make things look white. It shouldn’t be too surprising that domestic bulbs are about 2700K while office bulbs are higher, like 5000K.

It turns out that there are actual health benefits to 2700K bulbs in a home.

The American Medical Association points out that higher color temps contain more blue light, and this can interfere with melatonin production.  This can interfere with sleep.
The AMA goes as far as to recommend that street lights have a color temp of no more than 3000K.
