What camera has the best color accuracy?

[J A C S]

LED has non-uniform spectrum with a big drop between blue and green. Tungsten is much flatter.

There are LED lights available with a uniform spectrum output but they are costly.

The ones briefly mentioned as "not on the market yet"?

This video clearly illustrates why your statement:

Incandescent lights lean toward orange so they are no more "natural" than LEDs which lean toward blue.

is wrong.

Actually, our minds do not compensate for poor spectrum. We may learn to live with it to ignore it but this is another story.

Next, cameras do not need to compensate for color differences. After all, theoretically, our eyes will do it when we view the photo.

But with photographs, our minds do not compensate, probably because they aren't real. When I take a photo under incandescent light there tends to be an orange cast in the results. When I took the photo I did not see that orange cast with my naked eye.

Notice the greenish cast here. It did not look that way in person.

Notice these 2 photos. The first is under incandescent light, the second with flash. The flash photo is closer to what I saw because my mind doesn't compensate for the difference.

Hence the part that you snipped:

The problem is that the whole chain: cameras + ... + display media do not have the capability to present a (necessarily fake) copy of the real scene which will not distinguish from the real one even if they are designed to do it.

I was not referring to your link but the video that dealt with inconsistencies of the color output of LEDs vs consistent output of incandescent. Consistently wrong is still wrong. The advantage of incandescent is it can be compensated for more easily than with the inconsistent output of LED. I know you will still argue because for you it is more important to be right than to understand another person's point of view. You can have the last word because I find back and forth arguing a waste of time.

LED is bad not because it is "inconsistent". There could be just one LED light bulb in the world, and it would still be bad. It is bad because it has a very non-even spectrum, so it cannot be corrected to the same degree. So yes, how it can be compensated is the key, and no, it is not about inconsistency.

I read (I do not remember where) that in the early days of digital, tungsten lights were a major challenge but they seem to have ironed that problem out.

So while Neutral or Standard is often the most journalistically ethical choice, it’s not going to be always the most accurate. Different generations of LED bulbs can make some colors much brighter than in real life for instance…

LED and fluorescent bulbs are the worst. I always look for ones with the best CRI rating, but few bulbs even list theirs. And even CRI isn't perfect, it's flawed to start with and it's based on eye color response, not camera color response. When looking for accurate colors under artificial lights I always insist on incandescent bulbs.

Incandescent lights lean toward orange so they are no more "natural" than LEDs which lean toward blue. Sunlight gives the most natural color which should be obvious because sunlight is the natural light our eyes and brains adapted to. Anything else is not natural.

I guess the noise in the blue channel was too strong then because the sensor were more inefficient?

Highly probable. Unfortunately, I have been unable to find the reference. Be that as it may, continuous-spectrum sources like tungsten filaments, carbon arc light, and the sun remain the gold standard; these LED upstarts with their green spikes are still on probation.
