For example, see Rembrandt's portrait of an old man in a hat.Natural pigments now have synthetic siblings that greatly expand the earth color family. Synthetic iron oxides are the result of chemical processes and being human-made, they offer many color options.

This article will look at six QoR Watercolors, three with natural pigments and three with synthetic pigments. Paints with these names historically incorporate true earth pigments, and QoR is honoring this tradition. As highlighted in two of the paint names, these particular synthetic oxide paints lean towards transparency even in saturated washes. Some watercolorists like the results and behavior of natural pigments, others prefer the synthetics, and some embrace both.

The images below will provide a starting point for exploring the opportunities offered by our QoR iron oxide watercolor paints. These examples are painted on Fabriano Artistico lb. Cold Pressed paper. For the wet-in-wet examples, a brush was used to apply diluted paint to the center of a wet piece of watercolor paper and the test allowed to dry flat. Pigments have personalities, and the way the paint is milled and treated in formulations impacts how they behave in different contexts.

How an artist uses them can also influence paint behavior. Diluted more or less, applied to a tilted or flat surface, on textured or smooth paper, damp or wet or dry paper, intermixed with granulating or non-granulating paints: these are all conditions that may impact how the paint behaves on the paper.

This is demonstrated in our examples through the differences in granulation in the wet-in-wet examples versus the washes. In the case of the graded washes, dragging the brush against the sharp edge of the paper at the start of the stroke removed some of the granulating pigment, resulting in a finer visual texture.

QoR Yellow Ochre Natural provides a semi-opaque soft neutralized yellow with a slight bias in the direction of peach in light washes.

The partial opacity creates a soft comforting quality to the color that continues even in the palest tints. This paint does not tend to granulate. Golden brown, transparent, and granulating, QoR Transparent Yellow Oxide offers a clear neutralized yellow tan in thin washes and a warm glowing yellowish brown when applied with less dilution.

Depending upon application, the granulation may range from moderate to very fine. QoR Burnt Sienna Natural is a semi-opaque red-brown with a moderate saturation that imparts a soft quality to the color.

Granulation is impacted by the handling. The pigment particles that sink with granulation may appear more brown and the finer surrounding particles more rusty, which creates a beautiful two-toned result.Pigment properties, like durability, light stability, chemical resistance and low toxicity are similar to conventional iron oxides.

They can color a wide range of products including paints and coatings, cements, plastics, paper, mulch and more. These quality attributes make them ideal for metal coatings, including automotive coatings. In combination with effect pigments they can be used to achieve Gold, Copper and Bronze metallic colored coatings. These natural iron oxides are known for their durability and are considered a permanent pigment. Ochres are lightfast with good chemical resistance as well.

Siennas Siennas are one of the oldest pigments used by mankind.

Burnt Siennas build on the lightfast and chemical resistance of Raw Sienna and add improved heat stability. Raw Siennas are naturally occurring iron hydroxides, which convert to iron oxides upon heat treating.

Burnt Sienna Burnt siennas are prime pigments used for stains and glazes in wood coatings because of their transparency and warm red tone. When people picture the woods cherry, mahogany and rosewood, they most often are picturing those woods stained with a Burnt Sienna.

Umbers Umbers are naturally occurring iron oxides that are highly valued for their transparency and neutral chromaticity. At higher temperatures, umbers convert to a red iron oxide, Fe2O3 chemical form just like a yellow iron oxide.

This heating conversion is normally referred to as burning, hence the term burnt umber. Raw umber is an excellent brown pigment and popular in the stain industry due to their semi-transparency. Burnt umber offers the best value in brown pigments. Burnt Umber has a reddish undertone and exhibit good heat stability.

Van Dyke Brown. Our BN is intensively milled to give better dispersion characteristics and color consistency than the real Van Dyke. Transparent pigments. All have high purity and are below new 90PPM total lead limits.

So is there anything you can do to make things a little more predictable? It's called P Numbers Side note: bear with me for this section - it sounds all a bit complicated at first but it leads to a very simple and practical conclusion The P or pigment number is found on the tubes of all decent quality paints.

Each pigment is given a unique number, sub-divided for clarity by the addition of another letter to denote a colour. If so, then you may be close to finding an alternative. Bear in mind though that many colours are blended from more than one pigment, so will have two or more P numbers.

Now you need to be a subscriber to the two Society's sites to access the full lists and to be honest, unless you are a chemist, the amount of detailed information would probably be overwhelming. The illustration below is typical of the labelling found on paints. You can see the P number on the label just above the barcode on the left. Alongside each photo are the P Numbers taken from their technical specification. You can see that each one is slightly different, reflecting the varying combination of materials in each version, even though they're all oil paints.

To print the full size earth pigments chart, set page orientation to "landscape" and print to fit page.

All "earth" colors have hues between deep yellow and scarlet with moderate to low chroma ; the umbers including mars violet have lower chroma than siennas and ochres. Why so many earth pigments? There's always competitor pressures, and the irrational consumer appeal of venerable or exotic paint names, to explain why some paint companies offer so many earth pigments. But iron oxidewith trace metals and water included, is a relatively inexpensive and very versatile pigment, and it creates colors in a color vision area that is especially sensitive to differences in color lightness and chroma.

This is why they are among the oldest pigments used in art. This term defines a fairly well focused color concept: a mid valued, moderately dull, semiopaque deep yellow at a hue angle between 65 to The name is derived from yellow brown limonite historically sometimes called "French ochre" found in many locations around the world, and easily manufactured iron oxide of the same color.

It has been used almost continuously in painting and fresco since antiquity, and this continuous usage has kept the color concept well defined. Variations in the paint lightness and chroma arise from differences in the presence of manganese, particle size, and pigment density in the paint.

The narrow wedge of color markers indicates that the hue is generally a cooler yellow than raw sienna. The pigment is also usually darker valued and is much more opaque. During rinsing, some brands will cling to the brush with an almost greasy tenacity. Most brands stain only slightly and lift fairly easily.
