For most of history, that simply was not the case. Carrots existed in many colors — purple, white, yellow, and red. The orange variety that dominates the world today only became popular in the early modern era, mainly thanks to Dutch agriculture, which I have mentioned several times already as highly inspiring.
During the 16th and 17th centuries, agriculture and trade developed rapidly in Netherlands. Dutch farmers experimented with cultivating different vegetable varieties and gradually bred more stable and tastier orange carrots.
And thanks to the strong Dutch trade and logistics network, which I have also mentioned before, orange carrots quickly spread across Europe and later to other parts of the world.
The orange color is also linked to a high content of beta-carotene, which the human body converts into vitamin A.
And just to add a bit more Dutch… who knows who is behind New York City? Today’s New York City was originally a Dutch colony called New Amsterdam. The Dutch founded it around 1624 on the island of Manhattan as part of the colony of New Netherland.
