I don't mean to sound argumentative and I hope someone has some info helpful to you, but how are we to know the color of your 32 year old boat? Boats colors change with time; owners repaint, gelcoat and paint fades, manufacturers use different colors, etc.
I'd be cautious in accepting anyone's suggestion that your boat is ______ color, especially if they have not personally seen, compared or tested the color on your specific boat.
