A wonderful dilemma to have: my advice is
Buy the first one, the deep blue. A beautiful colour. You mentioned you may keep the car 10 years. My taste changes every year, so what appeals now, may not appeal in 10 years. Go with a loud colour scheme and you may not want the attention in 10 years time.
Just my view. They are all great colours. I like the green for what its worth.
