PR101 + PY12*, Indian yellow by ShinHan (a great new paint manufacture of oil, acrylic and W/c paints) http://www.art-paints.com/Paints/Oil/Utrecht/Indian-Yellow/Indian-Yellow.html (and) http://art-paints.com/Paints/Watercolor/Daniel-Smith/Extra-Fine/Indian-Yellow/Indian-Yellow.html.
Notice that they sell from US suppliers. I used their Indian yellow oil color and it is perfect. They make this color in oil, W/c and acrylic. They are also the best supplier of Opera magenta (I can't seem to get it yet), their best because the pigment is a smaller size than other manufactures.

Orpiment was the first transparent dual-toned yellow than gamboge.
Gamboge is the color of dried ear wax in its mass-tone, milked from a tree called Garcinia hanburyi.
Buckthorn was another tranparent yellow lost when the Original Indian Yellow replaced them.

Turmeric is another dual-toned transparent yellow and it was cheap, Original Indian Yellow replaced it because it was more permanent.

NY6, Saffron, Color dye extracted from the stigmas Crocus Sativa then precipitated onto lake base. Permanent.
Transparent orange to yellow Saffron from the blue crocus flower was expensive, 170,000 flowers equals 1 kilo of saffron. (quote, Iran)
