title: Return RGB values from Range.Interior.Color (or any other Color Property)
body: <p>I was trying to incrementally change the background color of a cell to black, and I found that the Range.Interior.Color method returns a Long which is seemingly arbitrary.  Looking at the documentation on MSDN, there is nearly nothing about what this number represents.  Is there a way to return the RGB value from this long.  I effectively need the opposite of the RGB(red, green, blue) function.</p>
