Here's what I found on yet another website....
"The Leopard 2 NL differs from its German counterpart in having a Dutch-designed smoke mortar system with six barrels on each side, a Dutch-built passive night periscope for the driver, a 7.62 mm FN MAG machine gun installed co-axially to the main gun and one further MAG for air defense, and Philips radios with US-style antenna bases. In January 1993, the Royal Netherlands Army announced plans to phase out 115 of its 445 Leopard 2 NL, which were sold to Austria, and to upgrade the remaining 330 vehicles to the standard of the German Leopard 2 A5. The first improved Leopard 2 NL were delivered to the Royal Netherlands Army in May 1997. These vehicles use the same German camouflage scheme, but retain the Dutch radios, antenna bases, FN MAG machine guns and smoke mortars. It is expected that the Netherlands will adopt the L/55 main gun for their Leopards A5 NL at a later stage. "
The profile seems to show a single clour overal, but the text says otherwise...
