title: Change embed pdfviewer in emacs
body: <p>Usually I read pdf with okular, for I can customized the background color and text color. Now I am working on latex with a preview pane on the right of the window, the background color is just too white!</p>
  
  <p>I need to change the color of the backgroud and the text color, or if I can change that pdfviewer to okular(need embed in emacs). </p>
  
  <p>I wonder how I can do this. I am using latex-preview-pane minor mode, and AUCTex on emacs 24.</p>
  
  <p>Here is the emacs window, the pdf hurts my eyes!</p>
