    Abstract: A see-through security element (2), a security document (1) and a method for producing a see-through security element (2). The see-through security element has a first element with one or more transparent first partial areas and at least one reflective second partial area. The see-through security element has a second element with one or more first partial areas, which in each case in transmission form a color filter matched to a respectively assigned color, and has at least one second partial area, which is formed colorless, in particular colorless transparent, or in transmission and/or reflection forms a color filter which is matched to a color which is not assigned to any of the one or more first partial area of the second element. The first partial areas of the first element and the first partial areas of the second element at least partially overlap.
