Its kinda like a tatoo...if you like it so much when you see it, then wait 3-6 months and then if you still like it so much you want it permanant then do it! Its your car doesnt matter where you get the color from as long as you still love it every time you see it.
AAAHHHHH! you have gone to the dark side...lol. Do what you want! That color looks great. Wish I had painted mine anything but candy apple red! I painted my wife's lincoln for her (had to replace a bashed fender) and her and the kids said to repaint my stang that silver color with the metal flakes. I am thinking about it! ::
When I painted my two Mustangs I had saved all the leftover base everytime I painted either a red or blue car/truck. Then on the 66 I added some Dodge candy-red. So if it's not gonna be a concours car don't worry about it. As long as you like it!
A little O/T, but the other day I was looking at a 70 FB 351 4spd a guy had for sale. 58k original miles, never updated. He had it painted because it orginally was that "awful grabber blue." It is now sort of a maroon with BIG metalflake. Didn't look right at all.
Most of the colors are closely related with different names anyway. That color looks very close to the red that's on my new F150. Even Ford uses the same color with different names between their product lines. I'm sure the other manufacturers do too. Mark is right though, it's an improvement any way you look at it.
