      '''
      Generates a matplotlib colormap from a single color.
  
      Colormap will be built, by default, from white to ``color``.

              1. Hex code
              2. HTML color name
              3. RGB tuple
  
          dark (bool): If ``True``, colormap will be built from ``color`` to
              black. Default is ``False``, which builds a colormap from
              white to ``color``.

          colormap: A matplotlib colormap
