01 / Input

Start with a real building photograph.

The tool is built for architecture photography rather than generic image sampling, so the output is organized by spatial role instead of decorative swatches.

  • Use daylight facade photos for material decisions.
  • Use blue-hour photos for glass, shadow, and lighting studies.
  • Crop out unrelated sky or street clutter when the building surface should dominate.
02 / Output

Read each color as an architectural role.

Each dominant tone is mapped to facade, base, shadow, accent, interior, or landscape guidance so a palette can become a design note.

  • Facade tones describe the main exterior surface.
  • Shadow tones keep massing and depth legible.
  • Accent tones mark entries, edges, and lighting moments.
03 / Export

Copy variables into design systems.

The generated CSS variables give teams a quick handoff format for mockups, documentation, and visual comparison.

  • Use variables in concept boards and prototypes.
  • Keep the original photograph beside the palette for context.
  • Compare multiple buildings by reusing the same role names.

Process

Use the page as a working checklist.

01Upload one photograph

Choose a JPG, PNG, WebP, or GIF under 10MB that clearly shows the building surface.

02Review dominant roles

Check the measured share, matched color name, and guidance for each architecture color role.

03Copy CSS variables

Use the exported variables as a compact handoff for design studies and front-end prototypes.

FAQ

Quick answers for architecture palette decisions.

What is an architecture color palette?

An architecture color palette is a set of building-specific colors organized by spatial use, such as facade, shadow, base, accent, interior, and landscape.

Can I generate a palette from any building photo?

Yes. Clear facade or interior photographs work best because the extracted colors reflect material surfaces and light conditions more accurately.

Why does the tool match Chinese traditional colors?

The matches give each measured tone a culturally grounded name and reference point, making the palette easier to discuss and document.
