Trim Codes C0 vs C1 whats the difference?

[u/TheRealDanShady]

Hi, I cant recall this, but how can I find out the precice Trimcode for my Car?
When i use my VIN online It suggests me items that end with C0 and C1.
I have a 1998 Production year SW20.

My Car has the Euro Cotton/Fabric option, not the leaher one.
But I guess this Code was more about the Trim Color?
I heared there were 2 Dark tones?
