# Stamen Map Styles (Toner, Terrain, Watercolor) carries the structure and Schematic Transit Diagram appears as the accent.
# Style descriptors only. This prompt names no artist, studio, brand or work.

Produce four original images that take their structure from Stamen Map Styles (Toner, Terrain, Watercolor) (style, 2010s–) and their accent from Schematic Transit Diagram (layout, 1933–).

## What to make

Make the kind of thing Stamen Map Styles (Toner, Terrain, Watercolor) exists for: when the basemap has to drop to black and white so strong colour can be layered on top of it, or when a location map on an invitation or a guide should read as a painting on paper rather than a data panel. Choose one subject and hold it across all four.

## Structure comes from Stamen Map Styles (Toner, Terrain, Watercolor)

- Toner is drawn in black and white with no grey midtones at all
- In Watercolor the shore reads as the soft edge of a brush stroke, and the paper texture stays visible as you zoom
- Watercolor renders water as blues mixed with turquoise and violet, and roads swing from orange to red brown
- Labels, lines and ground are separate layers, so a tile set ships with any of them left off

Composition: Hold the same map as three layers: ground, lines, labels. Drop layers as the data on top gets denser, so the map itself carries less. Type and lettering: Keep labels out of the basemap and add them back as a separate layer only when needed. Use one typeface and change its size by one step per zoom level.

## Accent comes from Schematic Transit Diagram, used sparingly

- Lines limited to 45 degrees
- Evenly spaced stations
- Color-coded lines
- Independence from geography

Let one material quality come from it: One color per line, white circles for interchanges, plain background behind.

## Colour and feeling

Build the ground on #E5C49F, carry the structure in #7FB0C2 and #111111, and let a single accent come from #e52d3f. These are read off real works, so a direction rather than a fixed palette.
Feeling to carry: technique, play, nostalgia, trust, calm.

## Where they fight

- Stamen Map Styles (Toner, Terrain, Watercolor) and Schematic Transit Diagram both belong to Information Design, so the difference is small. Push the roles further apart than feels comfortable.

## What goes wrong

- Stamen Map Styles (Toner, Terrain, Watercolor): Lay thin lines and small type over Watercolor and they lose to the soft edges and the paper grain, so nothing stays readable.
- Schematic Transit Diagram: Trying to keep a little geographic accuracy breaks the angle rule, and the diagram ends up neither accurate nor easy to read.

## Across the four

Keep the roles fixed in all four. Vary the framing, the scale and the arrangement so the set shows what this pairing can do rather than four versions of one picture.

## Constraints

- Do not imitate, reference or name any specific artist, studio, brand, character or copyrighted work.
- Do not reproduce the composition of an existing work.
- Produce original compositions in the general period languages described above.
