Shilesh,

In the Selenium-PT ink set the black is red/warm and the grays are blue/cool
so the transition tones tend toward a magenta or eggplant cast. From Paul's
test the grays held up so well I would have to say that the colorant there
is a pigment. On the black I have to wonder. Jon Cone has described the
additive to increase the Dmax as "dye stuff" although I believe is actually
a pigment but it is fading as if it were a dye. Whatever it is, it is dying
in Paul's fader in a fashion similar to Gen. black.
