Color Profile Matching

Let's say I was shooting in a venue where all of the cameras essentially see the same light, but are shot from varying angles and distances. Think concert or a stage performance of a play. How does one go about matching the color profiles white balance aside? I know/assume you have to do that.

In my situation, I would be shooting with a VG30 (probably a roaming camera), an a6300 as the "stationary" stage camera (the primary/only for audio?), and an a6400 likely on a Ronin S or SC. What's the easiest way to sync this all up color-wise as painlessly as possible? The good news, I guess, is that they are all APS-C Sony devices. I'd like to throw my EOS R in the mix, but I assume keeping them all the same is easier. Is it?

Sorry. I'm sure many of you do this all the time. I understand conceptually in my mind what I want to do. I just can't wrap my arms completely around the "how."

Thanks for any guidance. Looking for expertise.

One of the 'problems' of stage lighting is simply that there likely is deliberate introduction of color gels for dramatic lighting. What I would do if faced with shooting from multiple positions with a variety of cameras is to simply MANUALLY SET COLOR TEMP to a single value (such as 2900K if you want close to neutral; or to 3200K if you want some warmth to the lighting to be apparent).

Do I simply use a common color profile to keep it simple or do I have to shoot log and grade everything. I admit I've been lazy and haven't researched, but my bet would be that the VG30 doesn't have a common color profile with the rest given how old it is.

In a perfect world, what I'm trying to accomplish, of course, is that the output looks like it all came from one camera and not 3-5 separate machines.

If you think about it, you need to use a Color Profile made for EACH LIGHTING which you encounter...e.g. daylight vs. studio lighting vs on-camera speedlight, that a pro shooter would have a limited set of circumstances in which a specific color profile would be used.

In the field shooting situation is very different than described above, what one camera sees can be very different that what the same camera on the opposite side of the room sees, due to mixed lighting that usually occurs at a venue, whether it be the church or the reception location, each shooting position has its own uniquely different mixed lighting from camera position at different sides of the room and/or dependent upon subject position within the room. So under those high variability circumstances the use of a custom color profile is virtually impossible to maintain for a SINGLE camera -- let alone trying to match the results amount MULTIPLE cameras!
