[This answer][1] is really brutal on the eyes however I think it's key to have filenames and commands with that kind of formatting.

Maybe perhaps toning it down a bit? Similar in shade to the blockquote perhaps? Example:

`ouchy ouch commands hurt eyes`

> softer nicey nicey commands not so much.

Note: I am only talking about the background grey color, we should (for obvious reasons) keep the monospaced font for the code and commands.
