Change default color of Chrome when opening links in a new tab

On my box (ubuntu 12+) custom css is possible:
~/.config/chromium/Default/User\ StyleSheets/Custom.css
As for now, it's not (yet) possible for chrome://newtab/ , see http://developer.chrome.com/extensions/override.html for more information.
