making a paint decision

I was curious about how easy or difficult it was for any of you to choose the color on your a-body when it came time to spray
on some paint.
Did you know all along or did you change your mind a few times as it got closer to paint day.
I have had my project for 15 yrs and I find I haven't been
able to say this is the color I really want.
Other choices on the car such as engine, transmission, axle, wheels & tires I knew right from the moment I first saw the car
what they had to be to make me happy.
Paint color hasn't been so clear to me.
Like to hear how some of you picked your colors.
