Okay. I'm gonna have a go at this for ya Peter.
I think, as I understand the other 2 posts, they are talking about "artist's oil paints". No brand in particular. It's the "titanium white" that is throwing you.
I believe that that is the color of artist's oil paint that you want to get. Titaniun white.
You can get these artist's oils at any good hobby supply, Hobby Lobby, Michael's any arts and crafts store.
The brand doesn't matter.
I hope this is what they are talking about and it clears it up for you.
