Add some basic colors as tags?

Could we add some basic colors as tags? I think especily since we got banknotes with all sorts of different colors? Not all desciptions use the colors in them.

And for coins too, or at least something like “colorrised” as a tag for the colored/partially colored coins?

I think some “basic colors” could be:

Red

Orange

Yellow

Green

Blue

Purpel

Pink

Brown

Grey

Black

&

White

I know, of course this is not the basic/unambigius colors in all language.

What would that be for? There are many colored coins that have whole photos colorised, so they would have all or most basic colors tagged.

I was thinking mostly for the banknotes, although I know they are used across all catalogs, of course. 

But I can't see why not..? 🤔 Maybe just me who like colors and think we have all sorts of niche tags already? 😅

Color interpretation can be quite subjective, one man's green is another one's blue etc, and easily altered through oxidation and UV-exposure.

Those “tags” would be too large and too controversial.
We must keep tags for objects, places, etc, not for characteristics like colors, which are more “technical” (like shape, weight, etc)
