Districts
Neighborhoods with their own grain and color.
The places
Districts are the grain of a city — old town, docklands, the hill, the flats. Each one has its own hatch and its own color.
How to shade them
old town fine hatching, warm docklands blue wash, horizontal the hill green, contour-stippled the flats open, almost blank
Rule of thumb
Shade the difference, not the detail. A district is a feeling, not a fence line.
