I plugged a warm white dimmable USB chip style light into an old USB charger and left it in the bathroom. For reasons I don’t quite understand, my parents liked it so much they asked me for one.
I like the Maxxima MLN-50RWB, which has something for almost everyone - red, white and blue light. I like red but for reasons I don’t understand some guests greatly prefer blue. I’d say the white is neutral white.

It looks like they also make an amber night version and a different model also in amber. I haven’t tried those:
