Tunisia was interesting in a different way- it sits on the south side of the Mediterranean Sea.  Where the Sahara meets the coast presents a quickly changing climate to one of agriculture, though not a tropical paradise by any means.

 
The colors from that high up through an airplane window are faded through atmospheric water vapor, and though you can see all the features, enhancement still helps quite a bit.
 
The enhancement was really simple- I used a tool called Photo Impact, and then only Version 4.0, which is very much out of date.  However, it was simple to use and I just told it to automatically adjust brightness and contrast, and this was the result.  For some reason, Adobe's Photoshop has never done a good job with automatic brightness and contrast.  Strange that such a good piece of software in nearly every other way is so deficient in such a basic task.
