After doing some searching this is what I found out about the lower color you’re asking about.
There appears to be different color codes on the door tags for the different years of car. Paint code
73 was used for the 87 and 88s, Paint Code
76 for the 89s, Paint code
YJ for the 90s, Paint Code
YG for the 91s, and back to Paint Code
YJ for 92 and 93.
Take a look here
PaintScratch Touch-Up Paint (rs), Spray Cans, Spray Paint, Paint Pens, Car Paint, Automotive Paint
YJ= Grey Metallic Clearcoat
73= DUPONT COLOR: C8612
The other codes 76 and YG you’ll need to search.
