[Aquanet] mineral violet?

[pat davis]

Hi, Miriam

I went to the paints section at Handprint and below is the information I 
got. Mineral violet is the Maimeri name, but apparently it is PV 16 so 
the same pigment is used as shown by other manufacturers. I have not 
used any of these personally, however, so there may be differences.

FWIW
