Order of operations: noise reduction or color grading first?

[Gwendolini]

Hello.

Out of curiosity, is there a recommended way what to do first when it come to post producing video after the edit?

What I mean, is it logical to reduce the noise first an then grade the shots or is the other way around the better way?

Thanks for any insights in this matter.

The act of grading could hide, or exaggerate, noise so I would grade first and then do noise reduction if necessary.
