Blue on Blue or Black on Blue interior

[Montierth]

Hi all,
My truck is going to be bright blue metallic - like Nassau Blue. I am going to do the interior in a 1970 custom deluxe look. I am trying to decide between gray/black interior - or blue interior. I am leaning toward the black but my wife thinks the blue it "cooler" looking. After looking at the blues I'm finding it hard to match the carpet, seatbelts and seat cover together. Also a little afraid of being blued out! Any thots? I am including a few pics from others trucks I have found.

1st pic and 3 pic is the seat cover I going to order. The blue paint in the pics is close to what I will be painting.
