Produce four original images in the visual language of Stamen Map Styles (Toner, Terrain, Watercolor), a style from Information Design, 2010s–.

## What to make

Make the kind of thing this style 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 images.

## What has to be visible

- 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

Someone who knows this style should be able to point at each of these in the finished image.

## How to build it

- Layout and structure: 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
- Material and surface: Draw Toner as two values with no midtone. For Watercolor, scan washes painted on real paper and map them onto tiles through a scripted process, keeping the soft edges and the grain
- Colour: #E5C49F carries the ground, #7FB0C2 is the colour the style is remembered by, #111111 holds text and outlines. Read off real works, so treat them as a direction rather than a fixed palette.
- What it should feel like: technique, play, nostalgia

## What goes wrong

Lay thin lines and small type over Watercolor and they lose to the soft edges and the paper grain, so nothing stays readable.

## Across the four

Keep every cue above present in all four. Vary the framing, the scale and the arrangement so the set shows the range this style covers 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 language described above.
