Chromogenic peptidase substrates

There are fluorogenic peptidase substrates (e.g., Z-Arg-Arg-AMC) and
chromogenic glycosidase substrates (e.g., X-Gal) but I can't seem to find
any chromogenic peptidase substrates.  Anyone know of a source?  I need it
to go from one color to another, not simply producing soluble color from
precipitable color (a la azocasein).  TIA.
