I thought I bought a blue car. It was advertised as blue, paint job clearly said blue, the rendered image of the color was blue. My insurance paperwork states it is blue (as that’s what the NVIS calls it).
In real life, i have a black car. The blue pigment is so dark that is black, except in very specific, harsh lighting at certain angles. And then you can see it sparkles blue.
You know you can order vehicles from the manufacturer ahead of when you need it, right? Yes, there are stupid laws/rules in place that require a dealership to be part of the process, but you can generally pick what you want in a vehicle.
