title: I have a current function that needs to be changed to the description that I provided
body: <pre><code>def RGB2int(RGB):
      return RGB[0]*256*256 + RGB[1]*256 + RGB[2]
  #
  def int2RGB(i):
      return (i//(256*256), (i//256)%256, i%256)
  #create a function that differentiates between colors
  
  def colordiff(color1,color2):
      color1_int = RGB2int(color1)
      color2_int = RGB2int(color2)
      return int2RGB(color1_int-color2_int)
  </code></pre>
  <p>The formula you should use for your modified colordiff function, the difference color between color1 and color2, is as follows.  (Note: these are formulas, not Python!)</p>
  <p>If color1 has RGB values R1, G1, B1, respectively,
  and color2 has RGB values R2, G2, B2, respectively,
  then colordiff has RGB values Rdiff, Gdiff, Bdiff, respectively,
  where Rdiff = |R1-R2|, Gdiff = |G1-G2|, Bdiff = |B1-B2|
  Note: |x| is the absolute value of x</p>
