The colors of a map tile may give information about that region's predominant biome: its temperature, alignment, and other handy things. Cyan or blue means the area is "good" aligned. Purple and grey/red areas have "evil" alignment. Light grey, brown, and yellow areas usually are dry and have sparse vegetation. Green tiles have vegetation and are usually moist. White tiles indicate snow.
Tiles are listed in by alignment, with regular tiles first, then haunted, then good aligned tiles, and then evil tiles.
