Nickel Azo yellow (Transparent Yellow) PY150
Maybe I should admit right away: Nickel Azo yellow is my favorite among yellow colors nowadays. Previously, it had competition from Nickel Dioxin yellow (PY153) and Quinacridone Gold (PO49), but none of these colors are manufactured anymore, then Nickel Azo is a good alternative.
I have noticed that many people who buy the paint in a pan are surprised that it looks brown in a pan. Some even think that they have been given the wrong color, that it is an ocher or sienna, but that is what it looks like, brown in the pan but yellow on the paper. The reason why it looks brown is that it is quite dull in full tone but also that the color is transparent so that it gives the effect of brownness in the cup.
Nickel Azo yellow dries up with only a little lost value and hue, so there is not much difference between the color freshly painted and dried. In thick layers of color it is dull and seems warm in tone, while in thinner layers it has a beautiful medium yellow clear tone.
The pigment is very lightfast. It is staining and not granulating. Its main asset is the transparency that is unusual among yellow colors. This makes the color a good replacement for colors that no longer exist such as: Quinacridone Gold, Gamboge and Indian yellow.
Use the color for mixtures with both red and blue, you can get nice orange or orange-brown mixtures with Nickel Azo and different reds. With different blues, yellows and maybe with the addition of some red color, you get amazing greens. The color is really nice in different green color mixes.
Like all pigments containing nickel, the paint is slightly toxic. In normal use, the paint is harmless, but if you are allergic to nickel, avoid the paint for face painting.
The pigment is common as an ingredient in various yellow, green and orange mixed colors, but as an independent pigment it is unfortunately less common. I have only found eight manufacturers that provide the paint.
