I'm going through this right now and recently picked up some SEM paint I thought I'd try.
My "Trim Combination - Leather Neutral" RPO code is "522." The leather and door panels match the color of the upper part of the dash, including the cluster and radio bezel. The knee panel and glove box are lighter (52I) "Interior Trim Light Neutral."
So I bought the SEM 15883 Medium Neutral, and it's close. However, a direct comparison shows that it's off enough that I won't use it. In the pic below the SEM is on the left (on a sheet of ABS plastic) and the OE dash bezel is on the right. I'm not great describing colors but the SEM is a bit pink for my tastes.
I sent an email to SEM's customer service and they said the other aerosol that's close would be lighter yet, and if I wanted a better match I'd need to go to one of their dealers who can mix the right color.
