Explanation of Pigment Identification Chart
Permanency
(P Value) Scale
     
Pigments have been given a permanency rating by the ASTMD in their text Artists' Oil and Artists' Acrylic Emulsion Paints. The ratings are as follows:
1. Excelent 2. Very Good 3. Good 4. Fair 5. Poor
Transparency/Opacity
(T Value) Scale
     
From  1 or Least Transparent ( Most Opaque)
to         8 or Most Transparent ( Least Opaque )

 
Index Name
     
Manufacturers of pigments throughout the world have their products assessed and given a Color Index Name. This is an international code.
