Of course it negates the point of colored lights.  :)

Isn't that what I said?

Look, when we take a photo, we often do not want all the tone that comes from it. We white balance the photo. But sometimes we do want the tone that comes with it. So we don't white balance it.

I recently took a photo of some snow outside at night with a mercury vapor streetlamp for light. It was totally orange snow. Is that helpful? Is that the point? For me it was not at the time. Well, if it isn't, how do you fix it so it isn't orange anymore? That's all I'm showing.

I'm not saying you should remove the color. I'm saying you can. As an artist, you need to decide which techniques to use and when to use them. However, if you're an artist who doesn't know techniques like this, then you are a LIMITED artist.
