docs: Convert ints in the [0...255] range to the standard [0...1] range.
  
    Parameters:
      :r:
        The Red component value [0...255]
      :g:
        The Green component value [0...255]
      :b:
        The Blue component value [0...255]
  
    Returns:
      The color as an (r, g, b) tuple in the range:
      r[0...1],
      g[0...1],
      b[0...1]
