PR-264 Pyrrole Rubine Transparent

mstrick96

This is a result of my investigations into substitutes for alizarin crimson.  I've been using Mark's pyrrole rubine (pr-264) and also the Winsor Newton permanent alizarin (pr-177 anthraquinone red) and I like them both.  I've been making my paints and want to make these two up to decide which to use permanently.  

I found a source for the PR-177 at Kama Pigments, but am having difficulty finding a source for buying Pr-264.

By the way, I bought some M Graham Pyrrole Red thinking it was the same as Mark's.  Is is NOT the same.  It is PR-254 and is opaque where PR264 is transparent!  Checking on Dick Blick, I found that Holbein makes one using pr264 that they call pyrrole rubine transparent and that there are a couple of other manufacturers that use pr264 but give it a different name.

Does anyone know where I can but the PR-264 dry pigment in relatively small quantities?

Wow, that's great, @dencal. I went to the website and so many pigments I've never even heard of. Makes me want to make my own paints. It would be cheaper than buying ready-made tube paints but probably too time consuming.

Thanks @dencal.  However, what I see there is PR254, which is opaque as I understand it.  That had me confused for awhile.  I was trying to use Pyrrole Red paints and they weren't behaving like Mark's Pyrrole Rubine.

What I think I've figured out is that the Pyrrole Rubine that Mark uses is actually PR264 which is transparent.

Meanwhile, continuing my search, I found a source for the PR264!  Kremer Pigments has it and also has the PR177  which is the other one that is often substituted for alizarin crimson.  They are about the same price.  

@tassieguy, it's actually pretty easy to make your own paints and there are lots of instructions on the internet.  Kremer and Natural Pigments both have good instructions.  The hardest part is getting the paint into a tube, so I just use the small mason jars the way Mark describes in his instructions on adding the slow dry medium.

Here's Kremer's link to the PR264 pigment...
