This image contains a sample of the pigment "Purple Madder," which comes from the root of Rubia tinctorium. On the left is a small clear jar with a black lid, containing the powdered pigment labeled "Purple Madder." The label includes chemical formula "C₁₄H₈O₄" and the source ("Newman, London"). The jar has the number "104" printed on it.

On the right is a wooden or cardboard sample with two swatches of the pigment applied. The upper swatch is labeled "above - size," likely referring to pigment prepared with a sizing medium, while the lower swatch is labeled "below - linseed oil," referencing pigment mixed with linseed oil. The pigment appears in deep red-purple tones, slightly darker and more saturated in the lower portion.

To the far right is a small grayscale ruler for scale measurement, marked in increments from 0 to 40. The background is clean and white.

The image shows a glass jar containing a purple powder, accompanied by a label and a color chart. The jar is cylindrical with a black lid and has a label wrapped around it that reads "PURPLE MADDER" in bold letters. Below this, the label provides additional information about the product, including its origin from the root of Rubia tinctorum, its chemical composition (C14H8O4), and its location in Newman, London.

To the right of the jar is a color chart featuring three distinct shades of purple, each with a corresponding label.
