Exactly - I had the same feeling - plasticky - since this exact shade lacked 'depth'. I have the same problem with Guards Red. It's too light and again lacks depth. Carrara White can work but it needs an 'equally outrageous' body shape (which the GT3 has in spades).

Just my 2 cents but I only like Seal grey, GT silver and basalt black for a 987S. I'm so very sorry for suggesting such popular colours but they are so popular for a reason. I know you would like to stand out in some way. Why not do colour to sample?
