Put me on the list of "Not impressed with the grey."
Years ago I had a grey and white 35 Dodge, the white set off the grey, had it been all grey, I would have had to do something else with it.
My 49 Dodge pickup is painted with a 2012 -2016 Jeep blue. It really pops, and I get a lot of comments about how the people love the color. Most are surprised it is a modern color.
I'm with the camp that says pick something that is bright and pops, not something boring.
