+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.
+
+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:
+
+- Does it work in a color terminal as well as in the GUI?
+- 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.
