Not trying to start an argument or anything just trying to understand what’s right. Was looking at most recent Roger Gibson catalog and it has:

“NEW! Authentic Holley 340-6 and 440-6 carb base gaskets. Authentic dark color with “REAR” stamped into gasket as originals”

Is this wrong info?? Never seen the tan ones before this is why I ask. They’ve always been dark. The service manual also shows them dark.
