Original Color or change #2

My car is a 68 notchback Barracuda. It is UU1 metallic blue which is a very light color and has a black interior. Changing the color won't hurt the value as it was a slant six car and it is going to be a 360 V8 car. What I like is the 69 Metallic Turquoise (seafoam?) which looks greenish in bright light and blue in the dark. Keeping it the same would be easy but.... I did see a 67 Barracuda in the equivalent of UU1 shot with an incredible amount of metal flake that really stood out. The owner refused to say who painted it or discuss the formula used to get the effect.
