Just curious, but which color is the land, and which is water? My first assumption was that the dark color was the land, and the light was the water, but after continuing to look at it, I see that the opposite could also work.
Exactly my own thoughts
If i'd have to bet, I'd still go with dark = land, light = water
Interested to see where you go with this, so i hope you keep us posted...
