What factoon could this be?

Hi Guys, printed some Clan batttlemechs recently and could Not Decide in what colour sheme i wanted to Paint them...

Well so i gave them a sloppy Base with some Sand golem speedpaint and i have ti damit... I Like it

So this ist Just the First layer and all but it really reminded me of an old battletech book with Lots of Date Sheets in in (Guess the Cover was a brownish Timbie). Could you Guys Help me find any fiction that fits These colours?
