The Corvette looks interesting in that paint combination. I don't know how it would look on a Speedster. It's probably an expensive venture, and I would want to be very sure of my choices before I went ahead.
But, I guess that is true of any colour choice, isn't it? I'd keep searching for more pictures of two tone cars until I was quite sure of what I wanted.
I once had an MG-TD that I was going to do two tone - body one colour, fenders and running boards another. But a car such as that has a definite separation between distinct body panels. I ended up going with a solid colour. I had seen some older MG's that were two tone, and they looked okay, but as two tone was not an original TD paint choice, I stayed traditional.
However, it's all personal choice.
