I solved the blue one and drew up a map of the gunmetal. I've been stuck on the gunmetal for about 6 months. Can someone tell me what I'm doing wrong on my map please?

I put over 400 hours and can't solve the blue to save my life. Can someone please share the solution map please? This puzzle is really hurting my head

I put over 50 hours and can't solve the blue to save my life. Can someone please share the solution map please? I even tried drawing the map out on paper but still can't solve.
