Which parts are the inhibitors?

I know, I know, another Ritalin post. But bear with me. SWIM is either going to get plain Ritalin pills or, if SWIM can swing it, Aderall, in a few weeks but for now the Concerta is what SWIM's got, so he'd like to use it while he's got it.

Upon scraping off the outer layer of the pill SWIM found that it is divided into three different sections, each a different color. One side is a dark green, the middle is a peachy color similar to the outer layer of the pill, and the other side is white. Now SWIM is assuming that the white portion is the Ritalin and the other two are inhibitors, but he'd like to double check. Does anyone know?
