Agree because their dingo are very yellow, while the pickup is a sort of beige.

Some pics of the real vehicle.

For a Czech Dingo I used AK's British Sand Yellow. Photos I saw were more yellow than the US or German colors. That having been said, It looked like the Czechs used a different shade for each vehicle type.

Upon further review, seeing pics of Czech BMP2's in Afghanistan along with the MAXXPRO MRAP's they use my best guess is that it's painted in the same FS sand color that's used by the U.S.

One route could be: Find some photos of the real thing - select some which you have some reason to believe are reasonably good representations of the color(s) in use on that subject. This will be the color that YOU will try to match some paints to. IF ME, I would follow up by doing some homework on the web on paint company sites and maybe identify some near candidate from their color plates, or, if I just needed to "get painting now!", I would head to the paint locker and do a little mixing to make up a close match to my selected photo (or art pic) colors and get painting.

You MAY of course be able to locate some accepted "official color chip" to match some paints against. But this is seldom available to us modelers. And as we are talking paint color on a vehicle, there may be no really good info from which to determine what the real color actually was. Which leaves it up to the modeler to elect what his preferred color will be and go from there.

Kinda looks like the sand the Germans use since the Czechs are part of NATO.

But it's hard to tell from box art though.

Hello, please help me for a color.

What can be the right sand color for the czech army Hilux ?

The model is from MMK MODEL.
