After reading almost the entire topic it seemed very logical to me for TLG to use a main colour like violet, or lava-red/lava-orange, and
also include panels and stickers for a less bright colour scheme. Maybe a racing only version like the gt3 rsr wich already has a lego counterpart
that was displayed at different Porsche stands last year.
In my opinion this livery does in some way look similar to the prototype because it also has a black-white combination. Maybe this would be an option for those
who would like a completely white car and those who liked the prototype livery as they can use the optional stickers.
It would be a bit expensive as a b-model though i think.
