How to remove indentation highlighting in vim?

As I use vim, it tries to be helpful by highlighting groups of four spaces in yellow, as shown.

My .vimrc file says, in its entirety, set ta开发者_JAVA技巧bstop=4.

How can I keep vim from highlighting the indentation in my files?

Is this a case of highlighting the last search? If so, try typing ":noh".

If bentsai's answer isn't correct, then there's probably a match pattern in effect. In that case, :call clearmatches() will remove the highlighting.

Also, :set list will cause the tabs to get NonText highlighting, which might be yellow background. In that case, :set nolist will remove the coloring.
