Fairly astounded that MMC can't just provide the paint code ... what if they got the car back in for a bodywork repair or someone ordered a matching panel? ... or a customer says "I want my car the same colour as this one" .... can understand it for a car produced back in thw '50s but not for newer stuff.

They perhaps check the original build record if a car comes in for warranty work, or their paint shop mixing room most likely has a scanner anyway as part of the paint supplier franchise (used to be PPG)
Perhaps I can help a bit. (hopefully) My first Morgan's (a 1984) original colors years before it was destroyed. As importing Morgans to my country was
and still is, impossible at that time, the sweet Morgan
company at that time, was prevailed open to recreate the car as a "repair"
for which there is no limit under any national law. As I had the two color code numbers we had chosen for the earlier re-spray, that
was not a problem. Those colors have been copied by the Factory and other moggers many times since. Many gracious souls even ask out permission..which is the definition of genteel. Over time and other
morgans I have picked up some information of the intricate art of choosing car paint and the kaleidoscope of effects of different techniques and paint types. Fascinating!
The "names" of car paint are whimsical and woefully inaccurate as in "Maserati Marshmellow Primrose Yellow"

Car paint name are costless and they are chosen to please buyers. They
mean nothing They vary from car/paint manufacturer to others. True color codes are only accurate when the indicate paint manufacturer and their number. They may
or not match the qualities and hue of
another paint manufacturer and their number. If they do, it is a wonderful coincidence. There are scores of wildly different "BRG", as green is the national racing color of then England.
As well, colors may look identical in one lighting and not in another. For example, I gave the Works my colors from a vast book of Glasurit samples and they sent me back an ICI paint car. (car samples are
best done on sections of metal). I use both metallic and pearl effects and they do not travel well from paint supplier to paint supplier.
Scanning is more accurate but not perfect either. These brilliant scanners are scanning a car after it has been exposed to the elements for (sun especially) for a varying period. Each paint type and
each paint manufacture's paint has a differing vulnerability to such things. As colors subtly begin to change in hue and effect the moment it is first exposed to the world, scanning is best for touch-ups. Scanners
do not replicate the past. The scan what they are given to scan and try to match that to the data bank installed in their memories, often one paint manufacturers.
Only the original paint manufacturer and their code can do that.
They are the best for touch-up paint codes on specific spots. Additionally the MMC has changed paint suppliers over the years in hope of correcting defects, especially during the first 10 years of Superform wings. I dodged that by respraying my newer cars in the sturdier
paints of yesteryear. Modern regulations do not favor car paint durability, though I am very intrigued by this newer wave of ceramic coatings
If I have any of this wrong or there is something to add, there are professional car painters on this forum that can correct me.
