Parent album Farben meiner Welt, was released two months later and reached the top ten on the charts.

Mousse T., Walter Afanasieff, and Max Herre contributed to the project which took Catterfeld's work further into the R&B genre and introduced an adult contemporary edge to her pop sound.

While lead single "Erinner mich, dich zu vergessen" became her fourth top ten hit, the album's second and final single "Die Zeit ist reif" failed to reach the upper half of the German Singles Chart.
