Is raw brined pork with a very slight yellow tint and is no longer limp spoiled?
Color and texture are not reliable indicators of food safety.  You have to think freshness, temperature and environment.  If the pork has been kept in the refrigerator the entire time (under 40 degrees F), then it is likely safe to eat (given that you haven't kept is around for days before you brined it)...add to that, a briney environment...relatively high in salt content...You are not going to grow anything nasty in that.  I would say they are safe to grill, although, that's a bit long for a brine on pork chops. "No longer limp" tells me that you've begun to cure them in the brine.
