1. A see-through security element with a front side formed by a first main surface of the see-through security element and a rear side formed by a second main surface of the see-through security element, wherein the see-through security element has at least one first area and/or at least one second area, when viewed perpendicular to the plane spanned by the first main surface,
wherein the see-through security element has a first element, which has one or more transparent first partial areas and at least one reflective second partial area,
wherein the see-through security element has a second element, which has 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, 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 areas of the second element,
wherein the first partial areas of the first element and the first partial areas of the second element at least partially overlap when viewed perpendicular to the plane spanned by the first main surface, and
wherein, when viewed perpendicular to the plane spanned by the first main surface, one or more of the first partial areas of the second element at least partially overlap one or more second partial areas of the first element, and
wherein the see-through security element has a third element, the third element having one or more transparent first partial areas and at least one reflective second partial area, and
wherein the second element is arranged in the see-through security element between the first element and the third element, and
wherein the at least one second partial area of the third element is formed by at least one metallic layer or a sequence of layers comprising at least one metallic layer.
