# Second Empire (セカンド・エンパイア様式) — image generation prompt
# IndexStyle No.733 — https://indexstyle.org/styles/second-empire
# The entry name is a factual catalogue label. Generate only from the descriptors and rights boundaries below; do not imitate a named entity or work.

Use Second Empire only as the catalogue label for the sourced visual grammar below. Do not treat the name as permission to reproduce an artist, studio, brand, interface or work. Produce four original images using the described grammar, a style from Historical Styles, 1852–1880s. Treat the style as an art-direction system, not as the subject itself.

## Brief to resolve before rendering

Use any subject, deliverable, audience or format supplied with this prompt. If a field is absent, use the fallback below rather than leaving the decision vague.

- Subject: one concrete subject suited to concentrating a hotel's or apartment building's status at the roofline while gaining a usable attic story, or ordering a long historic facade into central, wing and roof hierarchies during renovation
- Deliverable: a campaign or editorial key visual
- Audience: a general contemporary audience
- Format: portrait 4:5, composed so the central idea can also crop to square
- Message priority: one unmistakable focal idea, followed by one supporting layer
- Rights boundary: identify what is factual research context and what will be newly invented for this output
- Representation: when a community, region or subculture is involved, state who is represented and avoid collapsing it into a generic costume or motif

## What to make

Choose one subject and hold it across all four images. Do not depict “a design style” as a mood board or a pile of period objects. Make a finished visual whose subject is clear without reading this prompt.

## What has to be visible

- A double-pitched mansard roof with a regular line of dormers
- Central or end pavilions projecting from the front
- A deep cornice carried on repeated brackets
- A symmetrical facade layered with quoins, pediments and iron roof cresting

Someone who knows this style should be able to point to the dominant characteristic and at least two supporting characteristics in every finished image. Distribute the remaining characteristics across the set when forcing all of them into one frame would weaken the composition.

## How to build it

- Layout and structure: Build symmetrically around a central pavilion, align the window bays, and close the top with a repeated rhythm of mansard roof and dormers
- Type and lettering: Place serif capitals once on the central axis above the entrance or within a pediment; do not introduce a new face on every floor
- Material and surface: Layer cut stone or pale stucco, a dark slate roof, cast-iron cresting and timber or stone brackets as clearly separated systems
- Colour: #D7C6A6 carries the ground, #53616B is the colour the style is remembered by, #5A3535 holds text and outlines. Read off real works, so treat them as a direction rather than a fixed palette.
- What it should feel like: luxury, trust, exhilaration

## Rights-safe interpretation

- The catalogue label and source materials are research context, not a request to reproduce a protected composition, proprietary asset or recognisable campaign.
- For a branded design-system entry, translate the documented hierarchy, spacing, colour roles and component logic into an unrelated fictional product. Do not recreate its logo, proprietary typeface, icon set, product copy, component geometry or page layout.
- For a regional, Indigenous or community-rooted entry, retain the stated place and historical context. Do not mix in unrelated cultural motifs, sacred material or generic ethnic symbolism.
- For a fashion or subcultural entry, use fictional adults with agency and avoid real labels, public figures, caricature and costume-like exaggeration that erases the social context.
- Treat any AI interpretation image in the dictionary as a browsing aid only. Build the output from the written characteristics and cited research, never by copying that image.

## Hierarchy and finish

- Establish the focal subject, reading order and negative space before adding surface effects.
- Make texture, lighting, depth and edge quality consistent with the material direction above; do not apply a generic cinematic or glossy filter by default.
- Gradients, bloom, glass, chrome, heavy shadows, film grain and distressed paper are off by default unless the material direction above explicitly calls for them.
- If an accompanying brief supplies exact copy, render only that copy and do not invent labels, dates or slogans. If it supplies no copy, omit text unless lettering is structurally essential; then use only short neutral wording and reject pseudo-text.
- Keep anatomy, perspective, repeated objects, borders and joins physically coherent. Reject visual artefacts that merely look decorative from a distance.
- Do not let the most obvious period prop or motif carry the result by itself. The style must still read through composition, type, colour relation and material behaviour if that cliché is removed.

## What goes wrong

Do not stop at adding a mansard roof. If window bays, central pavilion, cornice and dormers do not share one axis and hierarchy, the roof reads as a detached addition.

## Across the four

1. Canonical read — the clearest full composition and strongest expression of the visual grammar.
2. Reframed read — change crop, viewpoint, scale or negative-space distribution while preserving the same subject.
3. Material read — move closer and make surface, construction, texture or graphic detail do the work.
4. Reduced read — remove secondary elements and prove the style still reads through proportion, colour and one dominant cue.

## Constraints

- Do not use the catalogue label as a request to imitate 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.
- No logos, signatures, watermarks, branded packaging or recognisable protected characters.
- No proprietary font files, copied interface screens, existing product copy or exact component arrangements.
- Do not add period clichés that are not required by the visual grammar or the chosen subject.

## Final self-check

Before returning the images, verify that the subject is clear, the set is meaningfully varied, the dominant cue is visible, the palette has roles, any text is intentional, the research context has not become imitation or caricature, and none of the exclusions above appear.
