Historical appeal: Albertblue is a classic Porsche colour that is still highly valued by collectors today due to its blue elegance and historical connection to the Porsche brand. The dark shade of blue has been available since the 1970s, and both the colour codes and the availability on the respective models have changed over the years. In 1970, Albertblue was available under 1810 and 1818 for the 911 Targa and the Coupé. This was followed by the 911 in 1972 under the colour code 325 and the 928 in 1978 under the colour code 387. Albertblue is a rich, non-metallic shade of blue. The colour nuance is between navy and medium blue.
