Default paint mixing, named colors


| I think you're right. My local Sherwin-Williams store has had such a
| device for years. Take a color sample to the store and a digital
| colorimeter will measure the color and automatically add the correct
| pigments to the base white to reproduce your sample color with amazing
| precision.
|
|
| forgot about that, they have been doing it for a long time
| my thoughts were around expensive fine art paints where you have several
| paints that are typical mixed by trial and error or memory of past trial
| and error
|
| you could have a software with a chromaticity diagram where you add
| paints and mix them oriented to an end user like a fine art painter
|

I buy a fair amount of paint for my work and
have had a lot of computer matches in the past.
My experience is that a computer rarely gets it
right, and even then it's only with off-whites.
I don't try to get a match unless I know the clerk
doing the matching and know that he can/will
tinker with it to get it right. Some things just
don't lend themselves to automation.
