Re: tricolor gum question - yellow



Actually, PO 49 (quinacridone gold) hasn't been manufactured since 2001. Daniel Smith bought up a lot of the available supply at that time; I was told then that there was enough to make paint into the foreseeable future; the person I talked to said "Don't worry, we've got plenty." I haven't checked back since to see how their supply is holding out. But don't buy it, because Keith and I want it all.

I love Daniel Smith quinacridone gold. While I use 3 blues and 8 or so reds, the only yellow I use is the Quin Gold. Very transparent. Warm, and not garish.

Don't buy it though. Rumor has it that the pigment was created for the automotive industry (that gold PT Cruiser!) and that it won't be made anymore. So I want it all for myself!

Cut your pigment in half. With some yellows, I may even
dilute 1+30! Don't have my calculations in front of me but
I know PY150 is a strong yellow and needs quite a bit of
dilution. Never have used cad yellow tho I like its
color..because I don't do yellow as a first coat ever
because it's hard to eyeball registration with it.
