If it was me I’d probably shoot clean (no filters) and do the color grading in post. Sure, you can warm up the look with in-camera tweaking and/or filters in front of the lens but you need to be using a broadcast monitor during your setup to make absolutely sure the changes are actually going to get you the look you’re after. Normally the only hard filters I ever use are grad NDs or polarizers (for rejecting reflections in glass or water).
Interestingly enough, I find the unaltered EX picture to be quite neutral rather than being too bluish or reddish. For me that’s a good thing because it takes a lot less work in post to achieve what your final look will be.
