I'll go crawl under the white wagon and see what colors finally sealed mine. I had all kinds of trouble hitting on the correct-for-me solution.
Will edit my findings........

Green on the driver's side
Red on the passenger side.

Looks like I have a leak after 3 years. I added a can last week and have oil residue back on the compressor that I had just wiped off. I tightened the 15mm "single" bolt just a bit......

When I bought my Four Seasons compressor, it came with only green and red seals, but they were clearly not the correct combination. I had to procure the suction side seal from the local NAPA store. Part #TEM 407279.

Yep, you have to really closely measure the connection of the stepped port compressor and manifold lines. I don't believe all applications are the same based on different combos folks have had to use.....

On my compressor, the diameter of the seal recess was much larger on the suction side as compared to the discharge side, making the red seal much too small. Likewise, the diameter of the yellow (gold) seal was larger than the red or green seals.
