title: How to fade color from white to black?
body: <p>I have a timer that's fading a color from white to black, but I'm having some issues.</p>
  
  <p>I have an array of ints to represent the RGB values.</p>
  
  <p>I have a timer which runs every 100ms and decrements the RGB value in the array.</p>
  
  <p>The problem I'm having is that I will end up with other colors in the middle, green yellow, red, etc.</p>
  
  <p>What I am trying to do is to fade from white to black, so I need the color to become a different shade of grey as the timer runs.</p>
