To the best of my knowledge it can't be done. Any copper on a layer will be that layers colour.
Its always difficult to adjust to a new tool, but you'll eventually get used to it, pads are distinguishable by their shape, so that's how you spot them.
The only other thing I can suggest is go into design rules and increase the solder mask expansion rule to something greater than 0. Also ensure that the top/bottom solder layers are visible. This will give you an outline around pads the colour of which is the colour of the solder mask layers
