It arises purely out of the filtration used by the lab for C41 printing,
and is not a property of the film itself, just a workaround for the fact
that it's difficult to get a neutral greyscale print on colour paper with
this film.

You can achieve sepia, or much fancier split-tone effects in any colours
you want, within Photoshop or similar, starting from any greyscale image.
There's even a default action supplied for sepia 'toning', or you can
convert to RGB and mess about with relative densities of each of the
channels via curves.
