Naples yellow dark, a tremendous colour, although I am partial to yellows.
In masstone it is an ocherous, mustardy, yellow. It paints long in delicious, rich, brushstrokes. It is a reasonably strong tinter and the range of tints is pretty wide, the tints are pale, yellow/biege hues you would associate with raw sienna but they have more depth and richness.
In reality the paint is slightly higher chroma and more yellow and less pink than the swatch opposite, the tube photo is more accurate.
"This is the historical pigment (not a mixture of pigments to make Naples yellow hue) ground in linseed oil without any additives (e.g. stearates, waxes, etc.) or fillers typical of modern colors. It is ground on stone mills repeatedly to a smooth paste.
Hold the tube of paint in your hands and you will feel the difference from convenience hue paints made by other manufacturers—the genuine colour is so much heavier.
Load your brush with it and see the difference. Lead antimonate yellow has been made in various periods as early as the sixteenth to fourteenth century B.C.E. at Thebes. Lead antimonate yellow reached its highest popularity in European art between about 1750 and 1850 after which it was gradually replaced by chrome yellow (lead chromate) and later cadmium yellow (cadmium sulfide).

I've tried a few genuine Naples yellows from several companies & Rublevs are the best I've tried. Each of the three Naples yellows are stunning paints whether it's pigment loading consistency or just the sheer beauty of the colour. As I'm a big fan of Earth colours then this particular Naples yellow, the dark version, draws my eye more than the other two. The colour is very much like a dark yellow ochre with a touch of a red ochre. It really is beautiful to look at in mass tone & with an Earth yellow glaze, such as Hrazdan yellow it becomes even deeper & more intense. It sits somewhere between opaque & semi-opaque & handles beautifully making it a real pleasure to use & would be ideal for portrait painting adding some life into skin tones. Yes it's pricey & personally I'd recommend it only if you can afford it but the bottom line is wonderful quality from a company who provide arguably the best oil paint in the world.
