Khaki-Green aka SCC7 Mix: Humbrol 150+186 in ratio 4:1+touch black. Humbrol 86 is a fair faded match
Light mud is really SCC5 (Standard Camoflage Colour 5). Humbrol 84+ Humbrol 72 + Revell 45 in ratio 6:2:1. Humbrol 187 on its own is quick and effective.
Blue-Black is SCC14. Mix: Humbrol 33+67 in ratio 4:1 or straight Revell 9
Now these are colour matched to actual samples, so should be lightened a little for scale effect in 1/35th. Hope this helps.
