What is the hypothesis for colorful celery?

The hypothesis for colorful celery often revolves around the idea that different pigments in the celery, such as anthocyanins or carotenoids, can affect its color and potentially its taste or nutritional value. This could be linked to environmental factors, such as soil composition or exposure to light, which might influence the production of these pigments. Additionally, the hypothesis may suggest that colorful varieties of celery could be more appealing to consumers, leading to increased interest in their cultivation and consumption.
