1. A security element comprising a substantially flat substrate including first and second areas, wherein
the first area displays a first motif and generates a first color movement effect to be seen in the first motif while the substrate gets tilted over a first angular tilting range, wherein the first color movement effect produces at least one bright spot moving laterally over the first motif and simultaneously changing color while the substrate gets tilted over the first angular tilting range,
the second area displays a second motif and generates a second color movement effect to be seen in the second motif and within a second angular tilting range, wherein the second color movement effect produces at least one bright spot moving laterally over the second motif and simultaneously changing color while the substrate gets tilted over the second angular tilting range, wherein the first and second angular tilting ranges are different, and wherein the first and second color movement effects are identical with respect to CIE color parameters displayed, and
the first area comprises either a micro-mirror structure or a print of magnetically oriented pigments and the second area comprises the other one of the micro-mirror structure and the print of magnetically oriented pigments.
