title: Java BufferedImage getRGB method and Color class
body: <p>What do the x and y parameters in the getRGB(x, y) method represent? What does the numerical return value represent?</p>
  
  <p>How do I identify the color of specific pixels within a BufferedImage that is displayed on a DrawingPanel? Ideally I'd like to 'find' a word within an image, and underline or outline this word to create a relevant hyperlink. How can I translate these numerical values into human understandable colors like 'red' 'green' or 'blue'?</p>
  
  <p>Yes, I understand that in the Color class an alpha value of 0-255 represents transparent to opaque. But what does this imply for the actual color? I'm happy to clarify if this doesn't make sense. Thank you for reading.</p>
