That's a military desert sand color. Generally first seen on MOD Land Rovers in Iraq.
As for paint code....hmmm not sure there is on. Check military surplus vendors. That said Rustoleum does a Matt sand color in its camo range
A friend of mine runs a land rover / range rover specialty repair shop. Based on his experience, they are capable of stopping anywhere, anytime, at any cost.
I don't know about the brakes, only their unreliability.
