While I agree that the 6500 K is a blueish tint, it does work well to paint with it. I have used these bulbs in my paint area for a while now and can attest that they work quite well in that regard.
I like the 6500 out in the garage....but for the house it's too harsh...5000 is about as high as I will go...my wife prefers 2700.....so, in fixtures where you can't see the actual bulb I will sometimes mix them....
