In mixing flesh tones, Yellow Ocher (ochre) and Naples Yellow are essential . Many artists begin by mixing 1 part of Alizarin Crimson with 5 parts of either Yellow Ocher or Naples Yellow. To this, oil painters mix in lead white. If you need to darken the mixture, you can add either raw sienna or burnt sienna with a little Ultramarine Blue. Skin coloration varies greatly. To get the fleshtone that you desire will require testing.   The resulting color is your base fleshtone.

Yellow Ocher


Yellow Ocher (also spelled ochre) is one of the most common pigments used on any artist’s palette. Basically, ocher pigments are comprised of silica or silicon dioxide (SiO2) and clay – in short, sand and dirt. The iron minerals (iron oxyhydroxide or FeO(OH)) in the clay, which is finely ground rock, give these pigments their color.

Used since cavemen painted on their walls as well as in the tombs of the pharaohs, ocher describes a broad range of colors, which can vary in hues from yellow to orange to purple and to brown. Among those natural pigment paints described as Yellow Ocher or Golden Ocher (PY43 or Pigment Yellow 43), colors range from pale yellow to a golden yellow. Although many of the modern Yellow Ocher paints are made using synthetic pigments, some paint manufacturers, such as the Natural Pigments, LLC, based in California, still use natural earth pigments.

What makes Yellow Ocher so important to portrait painters is that its appearance, when mixed with lead white, closely matches the color of a wide range of fleshtones from paler Caucasian skin colors to the darker fleshtones of other races. Keep in mind that Yellow Ocher made with natural clay can vary in appearance, depending on where the clay was mined.  Yellow Ocher can also differ in their degree of transparency.

In mixing flesh tones, Yellow Ocher
and Naples Yellow are essential.


In addition to appearance, the composition of ocher oil paint can vary from one manufacturer to another. While the oil paints used by the Old Masters primarily consisted of pigments and oil, modern paint formulations include fillers and other additives. Because of differences in manufacturing, the same color from different manufacturers can differ in texture, hue, opacity and permanence.

Naples Yellow


Naples Yellow (PY 41) consists of the chemical compound, lead antimonite - Pb(SbO3)2 or Pb(SbO4)2.  This reddish yellow synthetic pigment has been used for thousands of years as far back as the ancient Egyptians and the Babylonians. Naples Yellow is manufactured by gradually heating lead and antimony, a silvery metal, to a high temperature. This process is called calcination.


The Naples Yellow pigment is opaque, lightfast and chemically stable. However, when any lead based pigment is exposed to polluted air containing hydrogen sulfide, it can darken.  As a powdered pigment, Naples Yellow should be handled with care because lead compounds are very toxic. In fact, all powdered pigments should be handled with care.

In matching fleshtones, I prefer
using either Yellow Ocher or
Naples Yellow. After mixing
a fleshtone, check the color
against your skin.

Naples Yellow can vary in shade from bright yellow to a reddish yellow. Similar in appearance to Yellow Ocher, Naples Yellow Dark gained popularity during the 16th and 17th centuries. Mixed with lead white, Naples Yellow Dark is helpful in matching fleshtones.

In the 19th century, this pigment lost acceptance with the introduction of synthetic yellows such as Chrome Yellow and Cadmium Yellow.



Essential Reading for Artists


One topic that fascinates me in the field of art are the materials and techniques of painters, especially the Old Masters. So much of what an artist uses and how he uses these materials affect the durability of the painting. Failure to understand the physical properties of pigments and oils used in painting, and how one material chemically interacts with another can result in problems. To ensure the longevity of a work of art, an artist needs to thoroughly familiarize himself with the materials, tools and  techniques of his trade. What's more, because many of these materials are comprised of toxic chemicals, he or she needs to know the hazards involved and how to deal with them. Here are four books in my library that I believe are essential reading for artists. 



The Artist's Handbook of Materials and Techniques


If you are an art student or serious artist, The Artist's Handbook of Materials and Techniques by Ralph Mayer belongs in your bookcase. Called the “Painter’s Bible”, this reference book explains the chemistry of commonly used art materials that you should understand. These materials include pigments, drying oils, solvents and varnishes. The Artist’s Handbook provides information on how to make your own paint and painting mediums, how to prepare a canvas and how to care for your tools. In addition to oil painting, Mayer’s book also covers tempera painting and encaustic painting. Originally published in 1940, The Artist’s Handbook has been revised several times. The fifth edition is now available.



The Materials of the Artist and Their Use in Painting: With Notes on the Techniques of the Old Masters


The Materials of the Artist and Their Use in Painting by Max Doerner, a German artist, who painted in the impressionist style, was an authority on the materials and techniques of the Old Masters. Originally, this book was published in1921. It is still relevant for any artist or restorer, who wants to learn the techniques used by the great painters of the past.


Painter's Handbook


First published in 1993, The Painter’s Handbook by Mark David Gottsegen provides artists with essential information about art materials. The book also offers step-by-step recipes for making paints, varnishes and gessoes. In addition, it explains how to prepare your supports and how to preserve, store and restore paintings. Gottsegen, who chaired the ASTM committee on artist’s materials, also covers the health hazards, which artists routinely encounter, as well as how to safely handle materials in your shop or studio.



Artist Beware, Updated and Revised: The Hazards in Working with All Art and Craft Materials and the Precautions Every Artist and Craftsperson Should Take


Often artists and art students are unknowingly exposed to highly toxic chemicals or work in poorly equipped studios. Gases, solvents, dusts and fumes can be toxic and threaten your health.  If you work with art materials, you need to read Artist Beware, by Michael McCann PhD. This book provides details regarding toxicity of chemicals, flash point and common uses for these art materials. McCann also explains what personal protective equipment an artist should wear when working with hazardous materials.
