11-6-12, I made an Acrylic Tartrazine Transparent Yellow.
This is how to make a true transparency test. First paint the color on white paper to see the color, then paint it on black paper. If it's truly transparent it should turn the black paper blacker.

5-10-13 Winsor Newton just posted this today. It's the same pigment Golden used in 2006, Quinacridone, Azo Nickel Complex Colour index name: PY150. The color is the same as the original Indian Yellow orange side which is called PY153.
"This year, due to the discontinuation of the current pigments, New Gamboge, in both Professional Water Colour and Cotman, has been reformulated again and, with advances in pigment technology, the colour is much closer to its original namesake, delivering greater authenticity." (I see it as Indian yellow orange side color, gamboge original was more to the brown side and not as transparent.)
So the new watercolor W&N pigment they call "New Gamboge" is a good synthetic, transparent, orange to yellow, duel-toned color. It also matches Tartrazine's PY100 color that I use in my plotter. I use a transparent yellow orange/side clear tint of PY:100 (PY100) Tartrazine pigment as an ink my wide format Roland giclee plotter and also as the basis my RCW primary transparent clear water color paints. 1/6/10 Ordering Page. |
It's called Tartrazine Acid Yellow 23 by SpectrumColors.com. It's also a food coloring pigment used by the Indian Ajanta Group, PY100. Anthraquinone acid dyes today constitute the second largest group of commercial colorants.

Tartrazine only dissolves well in water based paints. Here is a page all to the primary color Tartrazine yellow. I'm sorry to say it bleeds through acrylic medium. |
