Itsme:

I always preferred solid colours. My Porsches were speed-yellow, solid black and now PTS grau-schwarz (don’t know the English name).

If I will ever buy a Porsche again (bad dealer experiences) I will order a solid PTS olive green car (color code 274). There was a Swedish mini-series in TV (The Bridge), the female inspector had an old 911 in this colour. Perfect green for a classic 911. Black Fuchs wheels and some kind of brown leather, it can’t be better (personal taste)
