In a browser, hit http://localhost:5000/300x200 for example, or change bg and text colors by passing them as GET params:
http://localhost:5000/95x150?color=red&textcolor=orange
Leave off the second dimension for a square.
http://localhost:5000/200
Multiple image formats are supported. Just add an extension to the size (e.g. http://localhost:5000/300x200.gif) to get that format. png (default), gif, and jpg are supported currently.
See the ImageMagick documentation for the canonical list of colors. Hex colors are also supported, but with the # replaced with a !, like http://localhost:5000/400x300?color=!849593 In the future, hex colors may be the sole representation of colors.
