Taking a closer look at color-changing LEDs
Sure, these bulbs are smart -- but how accurate are those colors?

I have never really though of that.

Now that you mention it though, my wife didn't want to get white LED lights for the house because she said they look very blue. Which I guess is true for a lot of them. In fact, I did some research and it turns out that to get white light out of an LED, they mix blue and yellow together (which I guess explains how it could look blueish...)
