I've pixel peeped Porsche's different blue hues for far too long, especially the non-metallics. The new Shark Blue, which is reportedly a rebranded version of VW's Cornflower Blue, is quite intriguing. Grabber Blue is my favourite Ford blue, which may come as no surprise. The feel of Chief Blue for Jeep is comparable.
Plum Crazy is fantastic, much like how incredible Porsche's Ultraviolet on the GT3 RS is. An excellent orange is Go Mango. In the old Hellcat Redeye movies, I really enjoyed F8 Green.
Soul Crystal Red by Mazda is excellent. In a similar vein, the "Valencia Red Pearl" paint on an NSX caught my attention at an auto show since it appeared to be so deep. quite striking in person.
