I'm prepping my first M1 for NATO coloring. I'm using Vallejo's suggested colours. Black and brown look fine. The green however... it looks dangerously loud and garish, almost closer to Slimer from Ghostbusters.
This isn't my tank, but from someone elses build using the same colors...

I have primered and basecoated in black, but man.. there's no way I wanna put this green on.
