If you have a color temperature meter you can estimate how close the color balance will be. The closer to the tungsten color temp the light gets the more neutral the colors on the tungsten film become. It can be a bit tricky to get things just right with no knowledge of what color the light really is.
That said why would you want to make the warm tones of those times of the day go away? It would make the red toned sunset shot turn into a rather ordinary picture.
