code: def color_lerp(
      c1: Tuple[int, int, int], c2: Tuple[int, int, int], a: float
  ) -> Color:
      
      return Color._new_from_cdata(lib.TCOD_color_lerp(c1, c2, a))
docs: Return the linear interpolation between two colors.
  
      ``a`` is the interpolation value, with 0 returing ``c1``,
      1 returning ``c2``, and 0.5 returing a color halfway between both.
  
      Args:
          c1 (Union[Tuple[int, int, int], Sequence[int]]):
              The first color.  At a=0.
          c2 (Union[Tuple[int, int, int], Sequence[int]]):
              The second color.  At a=1.
          a (float): The interpolation value,
  
      Returns:
          Color: The interpolated Color.
