The tube saith: Vehicle: acrylic co-polymer emulsion.Pigment: Chromium/titanium oxide, PBr24, PW6. On the front: Permanence AA series 2.

I did some research on the water-miscibles, and those who use them seem to like them, but, like you, don't know whether to trust them. There's no getting around the fact that the jury's going to be out a while until a verdict can be rendered on the permanence factor. Several things give me hope. First, if you're careful not to add too much water, they have the same workability as oils; other oil mediums can be used with them as long as a 2-1 paint to medium mix is not exceeded; and lastly, re your concern, the water and the oil really do not mix. They've figured out a way to chemically suspend the pigment within the two liquids. After the water evaporates, the oil and pigment return to their usual relationship. (Approximately. I'm doing this from memory.) Also, the water-miscibles have the same drying time as regular oils, and apparently lack nothing in terms of vividity of color. The fast drying time of acrylics is one of the things I like about it, but it can also be annoying when you're trying to do certain things. Anyway, I was checking out Winsor and Newton's Artisan series today, and think in the near future I might give them a try. If I like oils, then I'll probably invest in the regular thing until that verdict comes in.

I don't really trust water miscible paints. I have not used them, but I am a third generation lithographer, and our family's fortune depended upon the principle that water and oil don't mix.

So, I am not the one to ask on that.

As for the acrylic, I don't think that lead pigments are stable in acrylic medium. See what the pigment number listed is (it will be PY and a number), and let me know (W and N are very good about listing things accurately). I can report to you what the chemical is, and its relation to the lead Naples Yellow.

Man, those are beautiful. Wish I had scenery like that around here.

Listen, I can't find an email for you so I'll ask here. Do you know anything about water-miscible oils, or have any experience with them? In short, can you recommend them?

Btw, I found a Winsor-Newton tube of acrylic naples yellow. The word 'hue' was not included. Does that mean I've struck gold?
