"P.Bl.1 is used in a variety of media. Incorporated in paints, full shades show excellent
lightfastness and weatherfastness, qualities which deteriorate rapidly as
more TiO2 is added. The pigment is tinctorially weaker than carbon blacks."

Pastel can't be tinted, so it might be OK in dark colors.

Re: Aniline black lightfastness?

They also use it very light colours.(almost white greys). Makes me think remove or not remove them my needs list hues looks useful. even more lightones. and there is in theory problem if another pastel what comes close this use titanium oxide goes connected this we have problems.

and i dont know when another brand where i think is similar greys without this (i think based what they tell pigments) is again special orderable form importer...
and currently looks i going avoid them.
