// Colors (experimental)
// Primary goal here: Keep text readable regardless of OS, terminal emulator
// and color scheme. Unfortunately I don't yet have a good answer, so this
// approach may yet change. Current approach:
// - Hardcode colors so that we can be sure we use legible combinations of
// foreground and background.
// - Use only the terminal palette in the range 16-255.
// - Not all terminals may support more than 256 colors. (I'm not yet sure
// everyone has even 256 colors. If you don't, please let me know:
// http://akkartik.name/contact)
// - Many terminals provide color schemes which give the ability to tweak
// colors 0-15. This makes it hard to assume specific combinations are
// legible. I'm hoping most terminal emulators don't tend to encourage
// messing with colors 16-255. (Please let me know if you know of
// counter-examples.)
//
// For now, you have to edit these values if you want to adjust colors in the
// editing environment. Check out https://www.robmeerman.co.uk/unix/256colours
// for a map of available colors.
