It could very well be that the green color is due to an alga living in the shell. Here in the Pacific Northwest our jingle shell Pododesmus macrochisma has a green color inside due to an alga living in the shell. If one can do, others can.

I collected  a green colored sayana  at Cape San Blas close to the shore in
sand just beyond the state park. It was the last shell I picked up before I
got into the boat and thought I had a real treasure.   I asked several
people what made it green and most thought algae.  I washed it with soap to
make sure it was in the shell and not just a coating.

Put it in a container where it could not possibly get any light and much to
my dismay the green faded out anyhow.
