Originally, whatever main turf ink color the parents have gets passed to the born inkling, at least the dominant part of it and not mixed, and becomes the birth color that cannot be changed no matter what. However, after reading the Volume 5 bonus chapter of the manga (even though the manga breaks other styles from the games), the birth color can be changed as long as the inkling is 7 years old below. Beyond that, he or she can't. In addition, the birth color of the assigned team leader automatically becomes the main turf ink color of his or her team during a Turf War League team registration. Otherwise, the turf ink color is randomized like the games. Rare cases such as having black or white tentacles but with the ink color always at the bottom (I'm pointing at Callie, Marie, and Pearl) can occur, but this has yet to be looked at closely so there's no info about that.
