title: Is there an easy way to compare how close two colors are to each other?
body: <p>Is there a way to compare how close two colors are to each other? If to say both of them are blue.<br>
  At the moment the way that we compare them is to manually assign each possible color to a color family(red, green, blue...). And then just compare the strings :)<br>
  But surely that manual task can be assigned to a neat little algorithm.</p>
