In short (click here for detailed version)

Carrots were originally purple due to their high content of anthocyanins, natural pigments that give them this color. Over time, carrots have been selectively cultivated to become increasingly orange.

Historical origin of the purple variety of carrots

Carrots were originally cultivated over 1000 years ago in what is now Afghanistan and Iran, and guess what: they were mainly purple or violet! The earliest serious traces date back to the 10th century, a time when both the leaves and the roots were eaten, but certainly not the flashy orange carrot we know today. These purple varieties, highly valued in Antiquity, gradually spread westward, thanks to Arab traders who transported them along trade routes. Since wild varieties were often whitish or pale yellow, growers favored darker-colored carrots in their selection, as they were associated with more flavor and better medicinal properties.

Natural pigmentation: role of anthocyanins

Purple carrots derive their dark color from a natural pigment called anthocyanin. This pigment, also found in blueberries and eggplants, gives them a distinctive shade ranging from deep purple to almost black. Anthocyanins primarily serve a protective role for the plant. They shield carrots from sun damage (excessive UV rays), cold, and even certain diseases or pests. For us, these same pigments are interesting because they possess antioxidant properties, which can sometimes offer health benefits. The darker a carrot is, the higher the concentration of anthocyanins and the slightly different flavor: a taste often described as earthier or more robust than that of the usual orange varieties.

Human selection and evolution towards orange carrots

Starting from the 17th century, Dutch growers gradually preferred to select carrot varieties with an orange hue, as these were sweeter, tender, and more pleasant to eat. This characteristic color comes from a pigment called beta-carotene, which is nutritious and rich in vitamin A. Through crossbreeding and selection, orange carrots quickly became popular, relegating the older purple varieties to a secondary role. Additionally, it is sometimes said that the orange color paid tribute to the Dutch royal family of the House of Orange, although this connection remains debated by historians. As a result, orange carrots eventually conquered Europe and then the rest of the world, almost making us forget that originally, they were generally violet or purple.

The presence of purple carrots in ancient art and literature.

In ancient Egyptian frescoes, purple carrots clearly appear as foods or depicted offerings. In ancient Persia, some accounts mention dark carrots, which were consumed for their medicinal properties. Even in the early Middle Ages, certain European manuscripts show stylized representations of purplish roots that closely resembled the purple carrots we know today. These artistic and literary mentions confirm that these dark-hued vegetables were clearly recognized and valued long before the dominant arrival of orange carrots.
