You should have plenty of pictures available online. There is also a pretty good youtube video on colors by Toyota Jeff that shows all of the GX colors when they were released. I think they've done an awesome job with the colors on this vehicle and the overall design. I don't think they make an ugly GX.
Black cars are not for everyone. Arguably the best color clean but it does take a lot of work. Even with PPF and Ceramic coating, it can still be a bitch to keep looking good.
I've owned dark vehicles for the past 15 years and was excited to get something lighter this time around to hide the pollen and dirt better. If you're keeping your vehicle in a garage, it makes black a bit more palpable.
Detailing our cars is something that has become a hobby of mine and if your concern is around scratches, or even any water spot, then a Black car will be your worst nightmare. It will show scratches and any artifacts pretty much immediately.
There is a saying "You don't own a black car, a black car owns you".
