How I can get a red light appear red, not white at night?
With my past or my Coolpix canons lit signs red white tent out. I can get rid of it in Photoshop, but I prefer not to.
A couple of things you can do. One is to ensure that correct your white balance. Try incandescent, fluorescent or possible. And the camera can be overexposure because of all the dark about the signs. Leave your exposure stop in time to make it look good.
