What colour would a flat world's sky be?

In continuation of my previous question, I'm wondering about the colour of a flat world's sky.

To recap the previous question, I'm imagining a flat world with the sun fixed relatively low above the center, with a number of large "sky island" type shades orbiting it to produce the day-night cycle. Here's a mockup map:

So, I'm wondering if the sky would necessarily be blue in this world, Rayleigh scattering being what it is. Further, would North America have a different colored sky than, say, the Wreath Peninsula? How much does it matter whether and how far the sun is inside or outside the atmo-layer?
