Eric - the mini cv33 was painted Italian Camouflage Yellow 3 (PollyScale #F505294). Note this is actually an aircraft paint shade, and although not officially slated for desert vehicles, it is possible to have been used on early equipment.
I got the idea after reading an entry on the Missing-lynx forum. A former Italian tank commander in North Africa was asked what colour their vehicles were painted. His reply was anything they could get their hands on, including paints from Regia Aeronautica and captured British depots.
The photo does not give a true representation of the shade (darn florescent lights) so I took another under daylight.

Jack
