My interior is "Standard Grey", color code TT.
The door sills and dash have turned brown, and the driver's door sill has started to crack.
It's becoming clear that this is a systemic problem with grey interiors.
My solution was to order a spray-on coloring kit from Leather World Technologies.
They sell color dyes based on factory color code, which is what caught my attention on my web search.

The color they sent was actually a bit dark and didn't match exactly. Probably due to the age of my interior, rather than any error on their part.
The customer service was great, and they took back the color and made me an exact match based on a sample piece of vinyl that I sent them with the return. No charge. The result was a PERFECT match.
They sell an aerosol spray tool (air brush) that worked great and applied the recoloring beautifully.
Of course, I had to take the door apart and tape things off to do the job right.
For the cracks in the driver's door, I used a leather filler and grain copier that they also sell.
While I was at it, I fixed a couple of worn spots on my driver's seat and sprayed it too.
Then I did my shift boot.
My car's interior now looks 10-15 years younger.
I haven't done the dash yet, because of the time investment I'll need to take it out of the car. Maybe I'll try to tape it off and spary it in place.
Wish I had taken before and after shots.
