Difficult to see planning mode buildings, pipes, etc. on mined stone ground

Something needs to be done with planning on top of mined stone ground - the gray on gray is hard to see and understand what is there.

This is a big peeve for me as well, it's impossible to see planning mode structures. I'm not sure how they could make them contrast though..

Yeah, we need better contrast or another color to clearly see the difference. ASAP.
