The image displays a small glass jar labeled "CAPPAGH BROWN (Natural Umber)" containing a brown pigment. The jar includes additional detail, listing its chemical composition as "FeO3&MnO2&H2O" and a reference to "F2, Weber Co." The label includes the number "12" written at the bottom.

Next to the jar is a swatch card showing the pigment applied in two different ways. The upper section labeled "above - size" shows the pigment mixed with a sizing agent, while the lower section labeled "below - linseed oil" demonstrates the pigment mixed with linseed oil. The swatch exhibits a rich brown color in both variations, with a slight sheen visible in the linseed oil portion.

A small grayscale ruler is placed beside the card for scale measurement, indicating size and providing a reference for accurate color documentation.

The image shows a jar and a swatch of pigment labeled "Cappah Brown (Natural umber)." The jar contains a brown powder, and it has a label detailing the composition of the pigment: "FeO3 & MnO2 & H2O" and "F2, Weber Co." The jar is marked with the number "12" written in white on its base.

Alongside the jar is a swatch illustrating the color of the pigment. The swatch is divided into two sections: the top section labeled "above - size" shows the pigment in a lighter shade, and the bottom section labeled "below - linseed oil" shows the pigment mixed with linseed oil, resulting in a darker shade and more textured appearance.

There is also a small color reference strip on the right, featuring varying shades of gray with markings denoting measurement intervals, presumably in millimeters.

Here is a description of the image:

The image showcases a sample of "Cappah Brown" pigment. On the left, there's a clear glass jar filled with a brownish powder. A label on the jar reads "CAPPAH BROWN (Natural umber) Fe O & MnO₂ & H₂O F₂ Weber Co." The number "12" is handwritten on the jar.

To the right is a vertical swatch that demonstrates the color of the pigment. The top section of the swatch is a smooth, solid brown. The bottom section has a slightly rougher, more textured appearance, suggesting a difference in application or material. The swatch also has a label stating "CAPPAGH BROWN" with text below indicating "above - size" and "below - linseed oil," suggesting that the top portion might have been applied with a sizing agent, while the bottom has been mixed with linseed oil.

On the far right, there is a color scale to aid in color referencing.
The overall impression is of a color analysis, comparing the appearance of the pigment applied in different ways.
