For some applications I do like the higher freq lights that mimic the sun but for living room type settings I actually prefer the yellowish light you get from incandescents.
Much like audio standards to oneself, many ppl got used to the yellowish lights for so long that the newer colour variations for CFLs were hard to accept.
In some situations, the warm white colour is actually easier on the eyes (i find the cool white light to be hard on the eyes reflecting off of white paper).
However, as household wall colours go, the more natural white light better compliments one's house colour choices as they are not painted with a yellowish hue. Something i've noticed since installing CFLs (cool whites) into the hallways.
