Question... Are you leaving the viewfinder open? If so, close the little latch.

If the ENTIRE photo has a cast to it, you can adjust white balance when you process (if you shoot RAW). I typically use a 3.0 ND filter and my photos always come out a bit warm... cooling off the white balance is easy to do.

But in your sample, it's not the entire photo that has a cast, you have a glob of purple. That's caused by light leak. If you're not closing the eye piece, close it. The light entering it is much brighter than the light entering the front of the lens. Another possibility is that your lens has light leak coming in the side or light is leaking into some other crack in your camera (much less likely).
