Thats a start. For color work, you can do it with PrintFIX PRO, as described 
below (may be valid with 3d inks, though some adjustments will be necessary):

Measure desired mat color with PFP, in the Tools>Measure screen. Note downthe 
Lab values of the matte (if doing several, start a log, read them in a known 
order, then open the log to get the Lab values)

To get a match to the matte, open a document in Photoshop in your preferred 
color space (which I will assume is AdobeRGB). Now open the color picker, and 
type in the Lab values that you measured (yes, its a pain that the picker 
doesn't allow fractional Lab values to be entered). Now paste the resulting color 
in the border area of your image file.

For a 'tint' (paler version) of your mat's color, use the same a and b, but 
move the L closer to 100 (to paper white, actually, can't go above that). If 
thats too saturated, divide the a and b to half the original (both closer to 
zero, whether positive or negative), as well as moving the L closer to 100. 
Subtle is good. If its hardly noticable, thats ideal.
