I am trying to figure out the correct color for a Tamiya Merkava Mk.1 tank.
I plan to build it pretty much out of the box with the decal.

The instruction said the color is XF-59, but it seems to be too yellowish. Most of the picture I saw has a hint of greyish green tone to the color and the sandy color is more related to the dust accumulated on the tank. I am thinking about sand tan from Vallejo and added a touch of grey and khaki to it. There is the Sina Grey primer from Vallejo but that seems to be for a later era tanks. Any suggestions?

I am also wondering do they have non-slip service on MK.1s ?

Thanks for your help.

Option 1: Humbrol Khaki Drill

Option 2: Testor's SAC Bomber Tan cut 50/50 with Header White

Thanks. I have main Vallejo and Tamiya paint, so may be I have to try some mixing to match these colours.

Maybe this one will look good?
