When I have a display that makes smooth fonts look nice, I'm partial to Go Mono Italic or IBM Plex Italic, depending on whether I'm looking for crispness or comfiness; I generally prefer serif fonts but IBM have done a really good job with Plex.

Most of the time though I use low budget laptops and prefer bitmap fonts. Terminus is my go-to if I need more glyphs, but most of the time I find works fine.

All these fonts have been italicized, I set it as a mistake once ages ago and liked it.

In terms of colours, I don't like lots of them. I have TERM set to vt100 and a few rules to stop them from showing up. So my foreground is #000000 and my background is #ffffc7. My wallpaper is either #ffccff (pink) or #ccf7f7 (blue), depending on my mood.
