Help! How to get natural, even colored lighting and not rainbow of colors?

I usually change the color of the lights to "Cold". It will give it a more fluorescent feel and you won't see the greenish tone so much. That being said, it won't look so natural? I don't know. But at least it looks more consistent. I'll see if I can find any screenshots of my sim's house indoors and post them here.

Here's an example during day time:

But I think it will look more whitish at night time especially if you use a bunch of ceiling lights.
