People like yellowish light for a reason. It's not perceived to be as "harsh".

Actually, I think it probably has more to do with the solar spectrum, which is biased to the yellow-green.

Not coincidentally, our eyes work best in that region. I think "whiter" lights tend to be more toward the UV side and thus are perceived as brighter and, as you say, more "harsh."

Personally I prefer a very bright white light, without flicker if you can find it.
