 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'.

+- Does it work in a color terminal as well as in the GUI? Is it consistent?

 - 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?
+
+- In general, test your color scheme against as many filetypes, Vim features,
+  environments, etc. as possible.

 - Do not use hard coded escape sequences, these will not work in other

+- When targetting 8-16 colors terminals, don't count on "darkblue" to be blue
+  and dark, or on "2" to be even vaguely reddish.  Names are more portable
+  than numbers, though.
+
+- When targetting 256 colors terminals, prefer colors 16-255 to colors 0-15
+  for the same reason.
+
+- Typographic attributes (bold, italic, underline, reverse, etc.) are not
+  universally supported.  Don't count on any of them.
+
+- Is "g:terminal_ansi_colors" set to a list of 16 #RRGGBB values?

+- Try to keep your color scheme simple by avoiding unnecessary logic and
