CH-53E colors Desert Storm?

Can someone help me sort out the camo colors used by USMC CH-53E helicopters during Desert Storm? I am building one of the Revell 1/72nd scale kits, nice plastic and decals but to me the color references seem suspect - and of course I do not have access to Revell paint colors anyway. Any pointers would be much appreciated. Thank you and best regards, Kent Wilcox
