Frequently roots contain pigments that can be yellow (carotin, xanthophyll)
as in carrots or red (anthocyanins) as in sweet beets.  They seem to be reserve
substances, which some plants store in the first year of life and then burn

carotene seems more the consequence of human selection. In other words humans
liked orange succulent carrots and increased by interbreeding their carotin
