Vim color scheme not showing up properly in Mountain Lion's Terminal.app

Question

EDIT: See my comment below before investing too much time.

I've read a ton of related questions on SE and have had no success. Everyone elses' problems seem to be solved by changing the terminal to 256 colors, or configuring Vim to use 256 colors.

Here is what I have done:

I've copied the blackboard.vim color scheme into ~/.vim/colors

https://github.com/nelstrom/vim-blackboard

Other color schemes render properly, it's only this one.

:echo &t_Co returns 256 in Vim

In bash echo $TERM returns xterm-256color

My ~/.vimrc is

  1 syntax on
  2 set nowrap
  3 set number
  4 set nocp
  5 
  6 " Expand tabs to 4 spaces
  7 set tabstop=4
  8 set shiftwidth=4
  9 set expandtab
 10 
 11 " Color scheme with black tweaked from xoria256
 12 " colo sublime
 13 
 14 " Color scheme I like a bit better :)
 15 colo blackboard

This is what it is supposed to look like:

This is what mine looks like:

But my other color scheme renders properly:

Answer 1

Exactly. This is a GUI scheme.

You could try the CSApprox plugin (there are a couple of others but that's the only one I can think of at the moment) to convert it to work in a terminal.

However, tis colorscheme is quite short so you could customize it by hand. Adding cterm[fg|bg] with a correct value to every line that contains gui[fg|bg] should be enough and not take more than 10 minutes:

highlight Normal guifg=White guibg=#0B1022 ctermfg=15 ctermbg=232

See this chart for the available colors.

Answer 2

If your terminal support high-color mode as yours, you can use the CSApprox plugin to automatically convert a GUI-only colorscheme for the console.
