What year did the Army switch from the brown shoulder marks to the black ones?

When the Army introduced the AG-415 mint green shirts, that replaced the Tan shade 446 shirts worn with the Army Green Uniform, the original shoulder marks were brown. When did the Army switch to the black shoulder marks?

I am totally unfamiliar with brown shoulder loop slides -- they never wore these on the tan shirt. They started with green ones on the mint green shirt, then stitched to black. Is this what you mean?

Sorry if I phrased the question awkwardly. Yes I am referring to the AG 415 shoulder slide on ranks, I saw some that appeared brown and someone referred to them as brown, but were in actuality green. What year did they change to black? And why?
