Rusty metal array

Part of a textured (square/cubic knobs) metal disc/plate (a manhole cover).

 

Whether this is a monochrome image might be a matter of opinion: some might see brown, orange and yellow present, while others might see brown with some slight variance to orangey-brown and yellowish-brown spots. (I have not included it in my "Monochrome" album of photos.)
