title: Changing highlight line color in emacs
body: <p>I installed emacs 24 and also installed <a href="https://github.com/bbatsov/prelude%E2%80%8E" rel="noreferrer">prelude</a> and I wanted to change the theme from zenburn to tango-dark. But the color that the line is highlighted is yellow and I don't like that. I want it to be like the gray color in zenburn.

  <p>What should I do? I prefer not to turn off the hl-line but when I tried that I saw that the space between parentheses () are highlighted with the same yellow color. (In zenburn theme that didn't happen). I also know that this is not part of the tango theme because when I run vanilla emacs(sudo emacs) with tango theme no such highlighting happens. <img src="https://i.stack.imgur.com/CRxbP.png" alt="tango-dark theme with hl-mode disabled">
