Why will it be blue? I thought it had to be more in the 15,000-18,000 k range to be blue. True. It won't be so yellow at 5,000 k. But, I thought 5,000 k is more of a cool white.

(I guess it really doesn't matter. I'm not trying to pick a fight or anything. Just want to make sure I understand what I thought I knew!)
