British Crusader (TANK not the F-8) colors?

Hi All!

I have a few questions about the british Crusader tank color/s I'm having fun with a quick build OOB italeri Mk.2 (as I learn it's more Mk.1 then Mk.2) I can say it's of good quality, the fitting is good and shows nice detail. Still not so sharp like Tamidragon but that's the only choice.

Well it should be a sand/tan like color overall. Any suggestions for the right color name-brand-nomber? Maybe I should mix it ?

Now as I would guess of using Tamiya's XF-59 for this desert color, some crusaders had splotches of a darker color. Was it dark brown (Testors - Military brown)? or dark green?

Thank's!
