Apache color change question

[sbenus]

Hey everybody. First time DCS skin editor here. Was wondering if there’s a way to easily change the basic green color on the entire Apache to a different tone or do I have to go and do it individually in all of the subtle green variations in all of the layers? Of course I would have to do it for each file but hopefully not in multiple layers of each file.

And second question is: I put all my squadron logos on the side of the engine exhaust and on the side of the area below the cockpit. Under which layers should I place our new logo so that the texture is on top of our logo but keeping it still visible through the texture instead of completely covering it up?

Any help is greatly appreciated. Best regards all
