Yo.

If you are referring to the con rod big end bushings, the color marking
defines the range of thickness of the bushings.

There is a table on page 3-145 of the latest service manual that gives these specs.

PM me with your email address and I'll zip you over a copy of that manual, if you need it.

Ciao.
