abbott.vim

abbott.vim is a warm, dark color scheme for prose and code, with pastels and pretty greens. It's primarily designed for editing files with a lot of plain text (i.e., Markdown or TeX documents), but it handles executable code well too. This color scheme draws inspiration from several sources, including memories of late nights working mathematical proofs—it's named after Stephen Abbott's Understanding Analysis, which I was studying at the time—and drinking copious quantities of Mountain Dew.

Screenshots

Because hey, it's a color scheme! That's what you really want to see, right?

Compare to screenshots from older versions to see how this color scheme has evolved.

Colors

This color scheme uses a 16-color palette that maps nicely onto the ANSI color palette, plus a couple of additional colors for terminals that allow them:

abbott.vim looks best where RGB colors are supported, either in the gVim GUI or in a terminal supporting true colors with Vim's termguicolors option enabled. You can use this color scheme in a 256-color terminal instead, if you like, and you'll get the following approximated palette:

The colors are pretty close, but the brown and olive colors are replaced with shades of gray since the XTerm 256-color palette doesn't have many shades of brown to choose from.

Features

• This color scheme is a dark theme that attempts to avoid excessive text contrast. Plain text is light green on dark brown to be easy on the eyes after long hours. Additionally, care has been taken to ensure the color palette looks decent in "night light" mode (e.g., with f.lux or other blue light filters enabled).
• This color scheme supports all highlight groups in Vim 8.2, as well as the Better Whitespace plugin.
• Additional plugin-specific highlight groups may be added in the future.

Options

This color scheme offers some additional features that are disabled by default because they may not interact well with all terminals or with other Vim color schemes. These features can be enabled if the user likes to live dangerously.

let g:abbott_force_16_colors = 1

If requested by the user, restrain ourselves to only the 16 standard ANSI terminal colors even if Vim thinks the terminal supports 256 colors. This allows the user to configure their terminal emulator to use the 16 colors defined above for its ANSI palette, allowing exact color matches rather than 256-color approximations even in terminals that don't support true color.

let g:abbott_set_term_ansi_colors = 1

If requested by the user, use our standard 16-color palette for the embedded terminal. We don't do this by default because unlike the highlight groups above, this isn't automatically cleared when another color scheme is selected.

let g:abbott_term_use_italics = 1

By default, Italics in the terminal are disabled since the default terminfo for GNU Screen renders italics as reverse video, and since other terminals like hterm may show artifacts when rendering italics.

let g:abbott_term_set_underline_color = 1

By default, the foreground text color will be replaced by the underline color in the terminal since if the terminal does not support setting the underline color separately, that color will be completely invisible.

let g:abbott_term_use_undercurl = 1

By default, underlined text will be used in the terminal in place of undercurl, because some terminfo entries cause Vim to think the terminal supports undercurl when it really does not.
