Just what I was looking for Postmaster, thanks!
This has however made things more confusing. the question now is wether my stamp is "dark pink carmine" or "Bright brownish lilac [pink lilac]".
Here is my red violet sc127 (left) and sc169 (right) which I'd describe as purple/pink myself but Michelin turns this into a challenge.

PS: older versions of Scott don't have an 169a yet.
