    Parameters:
      :r:
        The Red component value [0...1]
      :g:
        The Green component value [0...1]
      :b:
        The Blue component value [0...1]
      :alt:
        If True, use the alternative color instead of the nearest one.
        Can be used for dithering.
  
    Returns:
      The color as an (r, g, b) tuple in the range:
      the range:
      r[0...1],
      g[0...1],
      b[0...1]
