It's not important that we see colors differently, unless you are deficient in certain parts of the spectrum and your job involves color evaluation.

What IS important is that we have ICC standard monitor calibration, so that we evaluate color from the same *relative* frame of reference. You might adjust your images with more warmth than I would, but they're YOUR images, and I can only assume you used a calibrated, profiled monitor when adjusting them. At least, that's the assumption of most labs if you order "machine prints" or "no color adjustment" be done to your files. I calibrate my monitors monthly, and my prints are a very close match to them.

A key point of color management is to get printers and monitors to match closely, so the color you see on your monitor is the color that comes from the lab (within reason... It's never perfect). But it's also nice to see the color with a standard frame of reference to what another photographer or designer intended you to see... However you see color.

In the portrait lab where I worked, we tested folks' color vision when they applied to work in Color Correction. We calibrated/profiled all nine identical monitors to the same numerical aim points. We calibrated/profiled all 40 printers to match closely, as well. The result was that any of our color correctors could adjust a job and send it to any printer, with results that were within our tolerance standards.

Ahhh, important to those in business maybe.
A camera's color rendition is not important to me, neither is my monitor.
Just the view on A monitor, or the print. I'll either change it if I want to or live with it.
My colors don't have to be accurate to .000001 percent.
I will never calibrate a monitor.
I'm not that picky.
And since my wife is the only viewer who MAY know if a color is off, how would anyone know, other than me since they were not at the shooting location?
Only the photographer knows for sure, unless there is an obvious WB error.

Not everyone is as concerned as some of those in BUSINESS.

Can't resist, your Wife probably thinks you are "off color" anyway. Mine regards me that way!

Hahaha. Sometimes I am made aware of some of my comments, but rarely.

Addendum to my previous post:
Why do perfectionists believe that everyone should believe, work, and feel the way they do?

I'm no longer in the lab business, but I still want my prints to match my screen. Getting them to do that is easy and automated.

Because it's our genetic mission, maybe?

Maybe, sounds logical since it is so rampant.

You might want to take a look at some results from a Leica camera and lens. Long touted as the very best color rendition. You know how Germans are about engineering mechanical things!

You might photograph something that is a known color/color range like middle of the day blue sky on planet earth (with appropriate exceptions for known pollution sites). There are plenty of things that have known color -- as already mentioned human skin -- car tires, weathered asphalt, snow, brushed metal surfaces, etc.

Take for example this photo: https://s3.amazonaws.com/files.dpreview.com/sample_galleries/3180508572/9041518123.jpg?X-Amz-Expires=3600&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=AKIA4NPXSRZN2I2XWOXX/20211110/us-east-1/s3/aws4_request&X-Amz-Date=20211110T014402Z&X-Amz-SignedHeaders=host&X-Amz-Signature=c2722d367278e0a88668b39f4096742b68210b578620b1c8f27788a7c85fe6fe
which took me a few minutes to find in DPReview's sample gallery for the Nikon D5. Auto-WB did that. I don't personally know that dog but I'm betting I've met enough dogs to know that's not really a purple dog.

A purple dog I'll change, but my daughter may have dyed her dog.
Remember, I did say "to my liking". If a color is off by a few nanometers, I'm not going to worry about it.
Purple dogs, yes. A slightly off shade of brown, no.

None of those has a known color.

Human skin comes in many different colors, even on a single person. Car tires only appear to be neutral because they are so dark. Asphalt color depends on its composition. Many metals (bronze, copper, etc.) have definite color.

Even snow only seems to be white because it comprises specular reflections from the sun and the sky. But it can make a reasonable target for setting white balance. Just watch out for the yellow snow.

That link does not work. All I get is, "This XML file does not appear to have any style information associated with it." There is no photo.

They have a known limited color range and in the case of human skin for example a known average color. Any chance you did see the sentence I wrote and that you cut right before the one you quoted where I did say known "color/color range"?

From deep black to pale pink and white with lots of different yellow, red and brown hues in between? Asian, African, Oriental, Northern European, Native American, Aboriginal - a pretty wide range. How do you come up with a "known average color"?

You need to travel more.

And there is noting wrong with the dog's color. It is lit by the blue sky.

I listen to color experts like X-Rite who publish them. You can too.

So you don't believe your lying eyes?
