Well, you've defintely got me thinking there, as I shoot Portra 400 at 400 I'm of course aware nearly every other photographer uses it, but it's not something I'm self-conscious about.

As 'straight' as you can get.
I guess it depends where your headspace is. You think of 'colour palette' as inherent in the film, where I think of it as inherent in the photographer. The colour responsiveness of the film is incidental in my mind - you shouldn't be thinking "Well, Ektar is good with reds, so I'll shoot this scene with that. Portra is great with blues, so I'll shoot this scene with that." Or like I said in my first post, you'll just end up down the rabbit hole.
P.S. Ektar was still available at the time of this posting.
