A security element for securing valuable articles comprises an optically variable layer (18) that conveys different color impressions at different viewing angles, and a color-constant layer (17, 24). The optically variable layer (18) and the color-constant layer (17, 24) are stacked in a covering region (20), while at most one of the optically variable layer (18) and the color-constant layer (17, 24) is present outside (22) the covering region. The color impression of the stacked layers (18, 17, 24) in the covering region (20) and the color impression of the one layer (18) outside (22) the covering region are matched with each other when viewed at a predetermined viewing angle. Further, the color-constant layer comprises an ink layer (17) and a metal layer arranged below the ink layer (24).
