How to show the vim theme in its original colors using iTerm

Question

I have a Linux box,. I use "Konsole" application. Inside "Konsole" the original colorschemes for Vim always show up right. They are not limited by the color palettes defined by the Konsole. Anytime I change the Konsole colorscheme, the terminal Vim colors are left intact.

However, in iTerm I can never get the exact colors for the schemes. If I change the iTerm theme, the Vim colors get mixed up too.

Is there any way to show up the vim theme in its original colors using iTerm, the absolute colors?

:echo &t_Co

returns 256.

I recently asked a similar question which got migrated to superuser. My problem was that white actually gave me grey.

In my console there was a colour palette and X11 colour names were actually mapped to a position on the palette. Changing the palette changes the colour, the meaning of X11 White is rendered according to palette location 16 in my case.
