A fast, low-latency, open-hardware e-paper monitor and dev kit

I built a colorscheme for Vim [0] that is close to monochrome when I was worried about blue light (I've since had kids and now this kind of worry doesn't rate at all), and I basically use bold and highlights (I hate underlining, italics, and squiggles, but I think you can do all that too in the GUI version). I found it surprisingly usable.

> in the GUI version

or in the TUI version, in a terminal like Kitty.

I want to try some monochrome UI, but that amber is definitely not my taste. Let me see if there is a "paper-like" theme, or maybe I can make one myself.

Thanks for sharing! Would it be alright if I try it out during our livestream this week?

Hi Alex. If you are interested in showing VSCode, here are the theme and additional color settings that I use with my Mira Pro:

Possibly not the best syntax highlighting, but generally makes the UI legible.

Feel free to use.
