I'm looking for color schemes for my necron army I am starting....I like this almost greenish/black/gunmetal color. Anyone have an idea what color it is or how to achieve this? Chat gtp gave me a suggestion but idk if that is right.

I have been casually collecting Tyranids over the last 3 years. I hit it hard this last 10 months as my primary army.....I for fun added up all my points....4895 total....and there is soooo many I want still. I never expected to get to 4k let alone a second exocrine away from 5k. Haha
