From what I've found, Gold traps are called, “Gold gear”, Silver (found one on eBay) is called, “Silver Gear”. As for the Red and Green, I have no idea.

I don't think they really count as new attribute as much. Anyway, yeah I think they're just those new gears called the sliver gear and gold gear. The color on the green don't really mean anything. It's the symbol on it.
Yes, the symbols on them indicate what “color” the traps. The one that looks like a cross is a Gold trap. You can see this on some Ability Cards and Gate Cards that refer to gears. It says “(Symbol)(Corresponding Color) Gear.” You can see this in Khodok's post in the card section about the Gundalian Cards. Give it a look.
