title: Javascript - how to select part of an image to change color
body: <p>I have an image that is completely white. I want to select certain hexagonal sections to make them different colors, and then make the sections act like buttons that call different functions when they're clicked. I think I know how I would change the background color and make them clickable, but I don't know how to select a hexagonal section to change those things. Can anyone help me? (without jQuery)</p>
  
  <p><strong>EDIT:</strong> I figured out how to change set apart the hexagonal sections, and how to make them clickable like a button, but I can't figure out how to change the color of each part. How do you do that?</p>
