Brown Earthy,
neutral, understated and lovable
Browns are the earth from which everything grows, it is the rocks,
solid and timeless, it is the trunks of the trees, reach hinge for the
sky. Brown is not flashy, like red, nor attention seeking like bright
yellows. Few colors are classified in the color index as brown because
technically brown is always just a darker, more neutral orange or red,
and many colors many people would think of as being brown are
classified under red and orange. Sienna and Umber, however, are so
important as industrial pigments that they and similar colors
were given a class name when the color index was first established.
Raw Umber PBr 7
ASTM l
Chemical type and
description
Inorganic iron oxide. The traditional earths are all color indexed
under PBr 7 Raw Umber has been used since antiquity. It gets it's dark
color from up to 25% manganese dioxide. Some varieties may also contain
alumina and silica. These impurities give a wide range of colors from
the greenish ones most often found in artist's materials to yellowish
and even a violet-brown. One of the joys of making your own paints is
the discovery of all the various gorgeous earth colors available on the
market. Originally an Italian pigment (Umber is a corruption of the
Italian for 'shadow' referring to it's darkness) but these days the
best grades come from Cyprus. Raw Umber is a fast drier due to the
manganese content, and makes a hard and fairly flexible oil paint
Toxicity
Manganese considered toxic. Do not breath dust.
Media suitability
Linseed oil, Alkyd, Acrylic, Watercolor, Gouache, Tempera,
Encaustic, Fresco, Pastels, Chalk
Burnt Umber PBr
7 ASTM l
Also known (in the trade) as Turkey Brown
Chemical type and description
Inorganic iron oxide. The result of calcining Raw Umber.
Excellent grades come from Italy where it originated, but the best
grades come from Cyprus, hence the common trade description of 'Turkey
Brown'. The raw versions of this color were produced since
prehistoric times, but the burning to develop the color was
probably not started until the Roman era. Umber is said to mean
'shadow' , referring to the dark color. Industry uses huge amounts of
this useful color and it is available in the trade in many color
variants. The home paint maker is likely to use light (yellowish), mid
(reddish) or cooler darker versions according to taste. The range of
colors available in the pigment market is a revelation after the
limited choices in most artist's materials ranges. All versions are
very fast driers due to the high manganese content of all Umber's. They
make hard and fairly flexible oil paints. Before the availability of
special driers (also called siccatives) it was normal practice to use
Umber as a small additive in many mixtures (or Lead White) to speed
paint drying times. The old masters were very familiar with these sort
of techniques for 'improving' the limited paints available to them.
Suitable for use in all media.
Toxicity
Manganese is considered toxic. Do not breath dust.
Media suitability
Linseed oil, Alkyd, Acrylic, Watercolor, Gouache, Tempera,
Encaustic, Fresco, Pastels, Chalk.
Raw Sienna PBr
7 ASTM l
Also known as Italian Earth
Chemical type and description
Inorganic iron oxide. The best grades still are from Italy where it was
first used in prehistoric times. Color is distinctly browner than
Yellow Ochre and various shades range from quite yellowish to golden
and quite brownish. Excellent all round pigment of great permanence and
useful in all media. The roasting of the pigment, by the Roman era
produced one of the most useful colors available to artist's in all
situations so must be counted as one of the most significant events in
pigment history. This produces a wide variety of colors by varying the
temperature and length of calcining as well as the original pigment
color making light browns to fiery reddish oranges of great beauty. Raw
Sienna is an average to fast drier and makes a hard and fairly flexible
oil paint.
Suitable for use in all media.
Toxicity
Not considered toxic. Do not breath dust.
Media suitability
Linseed oil, Alkyd, Acrylic, Watercolor, Gouache, Tempera,
Encaustic, Fresco, Pastels, Chalk.
Burnt Sienna PBr
7 ASTM l
Also known as Italian Earth.
Chemical type and description
Inorganic iron oxide. The best grades come from Italy. There is a wide
variety of colors available from the so-called 'half burnt' light
browns to the fiery oranges beloved by artist's. Unfortunately there is
a price difference for the best colors and corresponding ignorance on
the part of some industrial suppliers so there is often difficulty in
finding the very best colors. Often industrial users may prefer the
less transparent redder browns and these find their way into artist's
materials. It is worth searching, or even paying 'top dollar' to buy
pigment from Winsor and Newton or another artist supply house that you
know has supplies of the best pigment colors. It is also worth hunting
down the many color variants as some are quite extraordinary. The
development of the Burnt Sienna's was one of the great moments in
pigment history comparable to the synthesization of Ultramarine, the
mixture of these 2 colors it should be noted also produces some of the
most delicate and beautiful neutrals possible. Burnt Sienna is an
average to fast drier and makes a hard and fairly flexible oil paint.
Suitable for use in all media.
Toxicity
Not considered toxic. Do not breath dust.
Media suitability
Linseed oil, Alkyd, Acrylic, Watercolor, Gouache, Tempera,
Encaustic, Fresco, Pastels, Chalk.
Mars Brown PBr 6
ASTM l
Chemical type and description
Inorganic synthetic iron oxide. Usually a blend of synthetic iron
oxides (PY 42, PR101, PBk 11) Produced in a huge range of shades it is
used more in industry than by artist's. Usefully extends the range of
browns to the artist and makes available dusky browns and smoky brown
types of colors that are less easy to find in natural earths. Also the
pigments are more likely to be consistent from batch to batch than
natural product. The darker shades can replace the toxic Burnt Umber
for those with sensitivities to manganese or simply prefer non-toxic
colors for various purposes. Mars Brown however often lacks the
beautiful transparent undertones loved in the Burnt Sienna's and
Umber's.
Transparent synthetic iron oxides are available but are usually more
expensive than the standard versions. Like all iron oxides, Mars Brown
is an average to fast drier and makes a hard and fairly flexible
oil paint.
Suitable for use in all media.
Toxicity
Not considered toxic. Do not breath dust.
Media suitability
Linseed oil, Alkyd, Acrylic, Watercolor, Gouache, Tempera,
Encaustic, Fresco, Pastels, Chalk.
Other Browns Let the buyer
beware
Van Dyke Brown also known as Cassel Earth or Cologne Earth
This disastrous pigment was an almost peaty earth with a percentage of
organic matter and bitumen. It fades, causes oil paint to crack or go
dark and should always be avoided as a 17th century experiment gone
wrong.
Asphaltum, also
sold as 'Mummy'.
Literally a tar product this color caused paintings to crack and
generally self destruct. Used to get an imagined old master look it
should always be avoided. As the pigment known as 'Mummy" also was high
in bitumen the 2 pigments (equally bad) were often given each others
names. Avoid at all cost.
Mummy, also sold as
Asphaltum and as Egyptian Brown
This pigment, mostly bituminous in make up caused paintings to crack
and
self destruct. It was literally Egyptian mummies broken up and ground
into a pigment and
sometimes sold under other names to avoid squeamishness over painting
with dead bodies. Artist's conveniently ignored the gruesome origins
but an outbreak of disease in London was (probably erroneously, but
fortunately) blamed on the imported foreign (and arab) artist's
pigment. Within a short time it was banned in England and the rest of
Europe soon followed. Never to be used again, hopefully.
Brown Ochre
Often a dull variety of Yellow Ochre or less commonly, Raw Sienna.
These days it may also be a form of Mars brown. An example of a name of
convenience that can apply to many things, however all of these sources
have excellent properties as pigments and may be used without fear.
