I think the pull grader manuals are blue .
I do have Parts books that are green with lots of info of how to stick CAT stuff onto other make equipment.

I have a greenish book that shows the attachments for D-75

Then you have to consider the reproduction books which seem to be either brown or a light grey http://www.ebay.com/itm/Caterpillar-D4-Tractor-Operation-Maintenance-Manual-Guide-OMM-Serial-6U1-7U1-/301150771176?pt=BI_Heavy_Equipment_Parts&hash=item461dfc17e8
I am sure there are others but that is all i can think of right now.
I had a Two Ton parts manual that was a dark Gray and it was a Orginial. It was bigger than most and large print in it. I gave it to friend restoring a Two Ton.
