Hi, I'm way late to this thread and wouldn't bother responding except that I think the indiscriminate (and no doubt inadvertent) use of marketing labels instead of pigment names has made this discussion difficult to follow, and may be worth a comment.

Katharine,

I'll take your advice on all-things-gum any way I can get them.

Your absolutely correct that the Quinacridone Gold I was disappointed with had no PO49 in it. It was a mix of PR206,PV19 & PY150.

As a follow up on my quest. I ended up with Nickle Azo, PY150 ( aka W&N Transparent Yellow ) and have been thoroughly happy with it on my tri-color & gum-over prints. It is nice and bright, not too green and does not leave any haze.

Thanks for your input, I'll try and be more specific.

Nickle azo is a great pigment, very intense. Not sure of the other brands but with the M Graham version I only need about half of what I normally use in PY97 or PY151.
