  # In addition to creating custom colors, you can call
  # any of the default 140 HTML colors(in addition to
  # RayWhite) seen here:
  # https://www.w3schools.com/colors/colors_names.asp  
  # 
  # When a default color is called it is created once and
  # then stored for each future consecutive use. To call
  # a color method simply use the ruby naming convention
  # for method calls, for example to use BlueViolet you
  # would do the following:
  #
  # +Rl::Color.blue_violet+
  #
  # You can also add custom default colors by adding it to the ColorList hash so that they can be called the same way.
