title: VBA to change cell color based on current color
body: <p>I'm having an a lot of excel spreadsheets with a color theme that doesn't match the color theme of my company. 
  For instance I need to change cells with a RBG value of <code>204,255,255</code> to <code>179,212,85</code>. Is there a way of doing it with a VBA?  </p>
