indoor lighting

I don't understand why most people especially here in America use the yellow color light.Even here inside this house most of the bulbs that my husband is using are the yellow colored ones which I do not like so much because it is kind of painful to my eyes that is why I always have my eyebrows crossed. If I am given a chance to change our indoor lighting then I would pick the white light color because that is what I am used to have back home.
