Naples Yellow Hue is an opaque warm yellow colour. A combination of pigments, it closely resembles Naples Yellow, whose name comes from its natural deposits in Mount Vesuvius, Naples.

As with all Winsor & Newton colours, every colour in the range is individually formulated to take advantage of the natural characteristics of each pigment and to ensure the stability of the colour. The vehicle (oil modified alkyd resin) allows the colour to dry quicker whilst retaining the other characteristics of conventional oil colour.

Because alkyd resin has physical properties that differ slightly from those of traditional oils, the pigment load is somewhat different as well. Experienced painters will notice slightly greater transparency compared to Artists' Oil Colour. The colour has been formulated to offer the greatest degree of tinting strength possible (consistent with good handling properties), and to take full advantage of the true characteristics of each pigment.
