I remember reading the landscape of roshar is inspired by the tidal pools and coral coasts, which ties into the crustacean-themed native wild life, and the soil-less rock floor landscape. The whole time I've been wanting to give the larger world visual a crack, and I tell you I had no clue where to begin. For me the coral coast is just an explosion of colors that make no sense. I struggled for a long time trying to follow the tidal pool coral reef thing, and eventually reigned it down to these 6 color tests. Truth be told they probably still need to be striped down to just 2 main colors with sprinkles of highlights. Honestly Mr. Sanderson, what were you thinking??
