Actually, I've heard of some folks using filters to balance the RGB
histograms so that they don't have one or two channels relatively
underexposed & noisy, then adjusting in post against a gray card or
some such.


Only necessary if there is a reasonable imbalance in the first place,


Candles & fire in general, incandescent light, "warm white"
lamps, --- nearly all your typical indoor lighting falls under
that heading.


I've covered that here in the past, YOU may want your candle lit photo's
etc. to look like they were shot in daylight, but I certainly don't, so no
filtration is necessary for me.


You're completely missing the point. Please read more carefully,
I am not, repeat, NOT saying your candle lit photos should look
like daylight.

However, with candle light your blue channel is *severely*
underexposed when your red channel is already at capacity.
To fix that, you need to reduce the light hitting the red pixels
very much and the light hitting the green pixels somewhat.[1]
I.e. you need a filter.

Of course you are free to use the white balance tools in post to
re-create the very red environment.


Even if you are going to make an imbalance in post-processing
--- starting from a balanced point increases your reach and/or
your quality.


You mean *IF* you are going to make an imbalance in post, *not* "even if".
Deliberately making the color balance wrong, when it is actually what you
want to start with,


There is no "wrongW balance. Digital isn't film.

is pointless.


Proving that you didn't grasp anything at all in this thread,
but wanted to jump on someone to prove you're better.

[1] Or you need to add green and blue light, e.g. with a
flash.
