Hello Beatrice,

Now that I have refelcted a bit on your comments, I favor a
tristimulus colorimeter which will read out coordinates in the "color
solid" that represents human color perception. These numerical
readings plus your own recorded comments will provide the body of
knowledge that you desire.

The instrumental measurements will make sense over time and will
perform another function for which the eye/brain is inept, i.e.,
remebering colors over time.

I am not current on instruments availble today so the following
constitues an area that were I you I would investigate.

 Konic-Minotla makes a non-contact tristimulus coloimeter Model
CS-100A which seems to have many characteristics that would be useful
in your application. I think an instrument of this type could be
adapted to the output of a microscope and could be used hand held near
the surfaces of paintings.

 See.
