You basically combine both colors to get the desired look. However mudtroopers really are a muted blue green, italian olive doesn't give you that. You can skate with applying 433u ontop of the olive as I did, you're in the ballpark.
Keep something in mind, Lewis told me they were doing sets of 15-30. The look and color is not gonna be consistent. Some where full oversprays, some where drive by sprays.
If it were me, 433u as a top coat should be mandatory level 2.
