Rhonda, this is totally off the subject but I noticed you are from Minnesota. There is a red/red GT/CS in a little town called Sabin (8 miles from Fargo). Original paint, interior, hoses, etc. Probably hasn't been driven in 30 years. Of course, the first thing out of the owner's mouth is "it's not for sale" but she was thrilled to show it to me once I told her that I didn't want to buy it...just wanted to look at it. If you ever find yourself in Sabin it's the 1st house to the East of the red house with the white fence (that's how small this town is folks). I stop in and see her every time I'm up there - just in case. Gotta have something to put that Nissan engine in. Just kidding - about the engine, not about the car.
Sorry for the ramble.
Anyway, back to the blue question. The paint usually looks light blue but how it looks depends on how it's applied and whether it's in the sun or the shade. Five painters can apply it and get 5 different colors from the same paint. Most of that is due to the color of the sealer and the pressure at the gun. If I'm not mistaken the original paint applied at the factory died quickly and flaked off thousands of cars. As the paint died it got chalkier and chalkier which made it whiter and whiter, so an older paint job will look whiter than a new paint job.
I know must of you keep your cars in a garage or covered in some way but that is especially important for light metallic colors and red. Sunlight kills those colors the fastest.
