README.txt for color scheme files These files are used for the ":colorscheme" command. They appear in the Edit/Color Scheme menu in the GUI. Hints for writing a color scheme file: There are two basic ways to define a color scheme: 1. Define a new Normal color and set the 'background' option accordingly. set background={light or dark} highlight clear highlight Normal ... ... 2. Use the default Normal color and automatically adjust to the value of 'background'. highlight clear Normal set background& highlight clear if &background == "light" highlight Error ... ... else highlight Error ... ... endif You can use ":highlight clear" to reset everything to the defaults, and then change the groups that you want differently. This also will work for groups that are added in later versions of Vim. Note that ":highlight clear" uses the value of 'background', thus set it before this command. Some attributes (e.g., bold) might be set in the defaults that you want removed in your color scheme. Use something like "gui=NONE" to remove the attributes. In case you want to set 'background' depending on the colorscheme selected, this autocmd might be useful: autocmd SourcePre */colors/blue_sky.vim set background=dark Replace "blue_sky" with the name of the colorscheme. In case you want to tweak a colorscheme after it was loaded, check out the ColorScheme autocommand event. To clean up just before loading another colorscheme, use the ColorSchemePre autocommand event. For example: let g:term_ansi_colors = ... augroup MyColorscheme au! au ColorSchemePre * unlet g:term_ansi_colors au ColorSchemePre * au! MyColorscheme augroup END To customize a colorscheme use another name, e.g. "~/.vim/colors/mine.vim", and use `:runtime` to load the original colorscheme: " load the "evening" colorscheme runtime colors/evening.vim " change the color of statements hi Statement ctermfg=Blue guifg=Blue To see which highlight group is used where, find the help for "highlight-groups" and "group-name". You can use ":highlight" to find out the current colors. Exception: the ctermfg and ctermbg values are numbers, which are only valid for the current terminal. Use the color names instead. See ":help cterm-colors". The default color settings can be found in the source file src/syntax.c. Search for "highlight_init". If you think you have a color scheme that is good enough to be used by others, please check the following items: - Source the $VIMRUNTIME/colors/tools/check_colors.vim script to check for common mistakes. - Does it work in a color terminal as well as in the GUI? - Is "g:colors_name" set to a meaningful value? In case of doubt you can do it this way: let g:colors_name = expand('<sfile>:t:r') - Is 'background' either used or appropriately set to "light" or "dark"? - Try setting 'hlsearch' and searching for a pattern, is the match easy to spot? - Split a window with ":split" and ":vsplit". Are the status lines and vertical separators clearly visible? - In the GUI, is it easy to find the cursor, also in a file with lots of syntax highlighting? - Do not use hard coded escape sequences, these will not work in other terminals. Always use color names or #RRGGBB for the GUI.
