yes, daylight balanced stock are much better on mixed light interiors. better to have a natural ambient light and let any tungsten sources go warm than gelling all the windows with cto. gym lighting is typically 4500k i think, or "cool white" as some manufacturers call it. this is a color temp that looks really cool on tungsten film, if you like the oh so hip steel blue look, but it also blends very well with daylight.David M.

Also it seems that many if not all school gyms have lighting more balanced for daylight as I have shot E100D in such locations without filtering and the colors look good.
