I need to get into the refrigerator in the middle of every night. So I go downstairs with one lumen at 3000k, open the refrigerator door and BAM, I can’t see nothing. I’m blinded by that freaking light. Three or four months ago I put these in. 2700k 90 cri. A normal base with a small globe to fit in there. There are some other options on Amazon also. Sphoon G40 1.5w Low Wattage Led Bulb Equivalent 15 Watt Standard E26 Base G14 Small Low Power Light Bulb, Frosted, Warm White 2700k, CRI 90+, 150lm, Pack of 2 Amazon.com
Mine uses incan bulbs with a Nd2O3 coating to remove yellow from the spectrum. The resulting light has extremely crisp reds and greens, basically all the advantages of incan lighting minus the yellow. It’s amazing.
Those Angry Blue™ emitters are good for dieting.
You take one look at the food and go, “Ecch, I ain’t eating that shiite…”.

Just my opinion, but the health of leafy greens (lettuce, spinach, etc) seem more obvious 4500K and above. Warm CCTs make them look browner and ded.
I think you are right and its not a coincidence that modern refrigerators that have LED use cool temperature LEDs. Food does look fresher.
But only with hi CRI and slightly negative duv. Lighting for meat counters or vegetable shelves in supermarkets is made in the same way: cool white, but slightly rosy and with high color rendering. Even in clothing stores this is already a thing. The light in the vast majority of fridges doesn’t even come close to this…
At least in my fridge the food looks pale and dead, due to non-vibrant ‘colors’. For looking at the cheese it is okay, but not for more.
All of these. Utility visibility is what these are all about - where is the X and the Y - with examination happening post-removal.
I’m personally OK with the ~6000K is in my refrigerator. Whatever CRI they’re using is better than the flashlights of a decade ago - more than sufficient.

Interesting. Ideally, with the correct lighting, its easy to tell old vs fresh meat. When I shop for poultry the old stuff looks grey and lacking red, while the fresher things look more pink.
“…as long as I can see where the cheese is…”

It must of course also be said that the use of such special light also has a simple background: To sell goods. Fresh and juicy-looking meat is more likely to be bought than gray and old-looking goods.
I also don’t know to what extent there are regional differences. The butcher’s shops in my town all have this kind of light. This is particularly noticeable because the sales area itself is normally lit with 4000 K LED or fluorescent lamps, which makes the rosy tint even more noticeable.
So you are saying cool white with high CRI?
Cool white, with high CRI and rosy tint. I don’t know for sure how rosy these lights are, but I assume at least at -0.01 or so, since I don’t have any measurements I can only guess.
Would be a great conversation anyway: “excuse me, can I just make a quick light measurement of this rosy meat light?”

You know you are a high grade tint snob and flasholic when you plan to emitter swap your fridge.

Cool
What I saw in many shops is that they use LED strip with white and red emitters interlaced together. This gives a meat fridge a red / pink cast and makes all meat look better than they really are. It could even be considered false advertising

Yes, this is also possible.
There are also emitters around (like 2835 FreshFocus by Lumileds) which produce this light which is needed for lighting meat and vegetables.
Mixing neutral and cool white high CRI sources create also negative duv (at least if both sources are at around 0 duv), this is btw what dual channel lights (especially with 519A emitters) do.

I look forward to Lumileds Fresh Focus Fish Spectrum to being on Hank’s secret menu 
Not on my menu 
When my fridge blew 1 inc. bulb I temporarily put led bulb, I figured, I’ll buy oem bulb and replace it, but as soon as my wife opened the door she liked the cool led so much better she made me replace other 4 bulbs with cool led bulbs. It is a lot brighter now. As far as finding things, i would find my beer even with no lights,
Cool LEDs are underrated. Seriously. I know 2700k has its benefits over 6500k but cool LEDs are used in many places and its for a reason.
