Summary:The invention relates to an optically variable security element (14) having an appearance that is visually different from opposite sides (16, 18). According to the invention, the security element (14) comprises a multicolour reflective area (20) containing two relief structures (24, 34) which are arranged at different vertical levels in the z-direction and form an upper relief structure (34), which is closer to the upper side (16) of the security element, and a lower relief structure (24) which is closer to the lower side (18) of the security element. The lower relief structure (24) is provided with a lower colour coating (26), which follows the shape of the relief, and the upper relief structure (34) is provided with an upper colour coating (36) which follows the shape of the relief. In the z-direction, a translucent coloured planar structure (44) is arranged at a vertical level between the two relief structures (24, 34), wherein the two relief structures (24, 34) and the planar structure (44) overlap in an
