title: How can I save a color as a PNG image with a specific hex code and dimensions?
body: <p>I'd like to create a PNG file from a specified hex code, width and height. The PNG file will simply comprise the solid color, with the specified dimensions.</p>
  
  <p>Example inputs include #CCCCCC (hex), 500 (width), 300 (height).</p>
  
  <p>That would yield a PNG file that's simply a gray (#CCCCCC) rectangle, with the dimensions of 500 x 300.</p>
