color issue with VIM and iTerm2

Question

I have a color issue on iTerm 2 (both stable and beta release) using VIM (last version).

This is a screenshot on iTerm 2 using vim-css-color plugin :

And the same on the Terminal.app :

As you can see, iTerm renders quite strange colors (and not only with this plugin, this is just an example). I've been playing with the contrast slider in iTerm2 prefererences and every Vim parameter i found so far (x-term-color-256, etc etc).

This is my .vimrc file : https://github.com/nanark/.vim/blob/master/vimrc

Any idea ?

Answer 1

A terminal with 256 color support (like iTerm 2) is simply not capable of displaying the full range of colors.

The css plugin uses a conversion to approximate the hex color code in the terminal. This was designed to work with the default set of colors used by xterm based on the comments in the code.

If you want an accurate preview, you should use gvim or macvim.
