Three axes, not thirty presets.
A style here is a composition rather than a filter: what the map draws, how the ground is lit, and what the whole thing is coloured with. Change one axis and you get a genuinely different poster.
What it draws
The vocabulary decides which features are worth a line. A mountain poster and a city poster are not the same drawing with a different colour — they are different maps.
- Base — lakes and rivers
- The water everything else sits on. Always drawn.
- Mountain — paths, summits, cols and refuges
- For terrain where the interesting features are the ones you had to climb to.
- City — streets in three weights, water and green space
- For a route whose shape is defined by the streets it followed.
How the ground is lit
The hillshade is computed from elevation data with a sun position you can move. It is an art-direction control, not a rendering detail.
- Off — no relief
- Flat ground. The route and the type carry the whole poster.
- Soft — high sun, true scale
- Shows where the steep ground is without shouting about it.
What it is coloured with
The palette is the ground, the shadow, the route and the type, as one set.
- Paper — warm ground, cool shadow, orange route
- Adret is the sun-facing side of a valley, so the route runs warm against terrain that runs cool.
One palette, for now
One is the honest number. Four earlier styles each carried a near-identical warm paper, differences of a couple of percent that read as drift rather than as art direction — unifying them is what makes the output look like one product. A second palette arrives when there is a genuinely different look to show: a dark poster, a cool one. Not because a vocabulary drifted.
