You did not specify the type of paint you are using. If you are using oils, mix Burnt Sienna with Gold Ochre and a touch of Titanium White. If you are using Vallejo Acrylics, Beige Brown is a good starting point. If you are using Enamels, go with the above suggestions of lightening Tan, more realistic than using commercial Flesh. Also, if using enamels and you want to flatten the paint, add a touch of Talcum powder. Make sure it is Talc and not Cornstarch. Hope this helps.
