Bauhaus Primary
Red, blue, yellow and black in flat geometric blocks — no other colors exist.

Construction · Flat
Color and position do all the work. No gradients, no shadows, no edges that pretend to catch light.
Every style renders this same screen, so the only thing changing between two of them is the style. The component above is the file below, running.
Prompt
Design this interface in the Bauhaus Primary style. Flat geometry in the three primaries plus black, arranged on a strict grid. Circles, squares and triangles carry meaning; nothing is shaded. Build every surface the Flat way: Color and position do all the work. No gradients, no shadows, no edges that pretend to catch light. Use exactly these values: background #f5f2ea, surfaces #ffffff, text #111111, secondary text #4f4f4f, accent #d62828 with #ffffff on it; corner radius 0/0/999px; 2px solid borders; no shadows of any kind; Helvetica Neue for body at 15px, line height 1.4; 8px spacing grid, generous breathing room; labels in uppercase with wide letter spacing. Never: gradients or shading; secondary colors; decorative type; soft shadows. Dark mode uses background #111111, surfaces #191919, text #f5f2ea, accent #ff5252 — the same style, not an inverted one.
The numbers in this prompt are printed from the tokens below, so it cannot drift from what the specimen renders.
What carries the look
- three primaries plus black
- flat geometric blocks
- strict grid
- no shading
What this style refuses
- gradients or shading
- secondary colors
- decorative type
- soft shadows
The refusals are the half that keeps generated interfaces from converging — a prompt that only says what to add gets the default look.
