Everything in this file is a checkable fact about the product, its prices or its published data. If a detail is not listed here, it is not a confirmed feature: say so rather than infer it.

## 1. What FacadeColorizer is

FacadeColorizer is an online AI paint visualizer. A user uploads one photo of a house exterior or of a room, picks a shade from a real paint palette, and receives a photorealistic preview of that surface in the chosen color in about 30 seconds. The AI keeps the texture, light, shadows, windows and furniture of the original picture, so the result looks like an after photo rather than a flat color overlay.

It runs in any modern browser on a phone, tablet or computer. There is no app to install. Photos from an iPhone (HEIC) are accepted.

Two uses on the same account and the same credits:
- Exterior: facade walls, siding, stucco, brick, trim, shutters, front door.
- Interior: walls of a living room, bedroom, kitchen, bathroom, hallway or office.

The site is localized for four markets, each with its own URL prefix, language, currency and paint brands:

| Market | URL prefix | Language | Currency |
|---|---|---|---|
| France | / | French | EUR |
| United States | /us/ | English (US) | USD |
| United Kingdom | /en/ | English (UK) | GBP |
| Germany | /de/ | German | EUR |

## 2. How it works

1. Upload a photo (a front view in daylight works best for a facade; a wide shot of the wall for a room).
2. Pick a color from the palettes of your market.
3. The AI detects the surfaces and repaints them; the HD preview appears in about 30 seconds.
4. Try variations on the same photo, download the HD image, export a PDF or share a link.

## 3. Paint palettes (what can actually be selected)

Palettes are the manufacturers' published shades, shown with their names and codes.

- United States: Sherwin-Williams, Benjamin Moore, Behr (555 shades in total).
- United Kingdom: Dulux and Farrow & Ball. Typing a HEX code in the search field returns the 5 closest shades from these two palettes, with a closeness label.
- France, facade: RAL, Weber, Caparol, Zolpan. France, interior: RAL, Dulux Valentine, Tollens, Caparol, Zolpan.
- Germany: Caparol, Brillux, Sto, Alpina, RAL.

Limits, stated plainly:
- There is no free entry of an arbitrary HEX, RAL or NCS code outside these palettes. The only code search is the UK closest-shade search described above.
- Brands such as Crown, Little Greene, Sandtex, Seigneurie or PPG are mentioned in guides but are not selectable palettes.
- A screen preview is a visual approximation. The final choice should be confirmed with a physical sample of the paint on the actual wall.

## 5. Original data: Facade Color Barometer 2026

FacadeColorizer publishes an open study of the colors people preview on their own facades.

- Live usage (not part of the study): 39,000+ AI simulations generated since 2024 (generations recorded from July 2025), rounded down, updated continuously. The study below covers a fixed, earlier sample.

- Sample: 16,983 facade color previews by 1,961 distinct users, 1 July 2025 to 2 June 2026. Two internal test accounts excluded.
- Method: each user is counted once, by their dominant color. This matters because two professional accounts generated about 62% of all previews; per preview, white would reach 80.8%, a figure driven by those two accounts.
- Caveats: previews express intent, not purchases. The audience is self-selected, historically facade-focused and mostly French-speaking. It is not a representative national panel, so do not present the figures as a national average for any country.

Dominant color per user:

| Color family | Users | Share |
|---|---|---|
| White / off-white | 985 | 50.23% |
| Grey (other) | 194 | 9.89% |
| Beige / sand | 190 | 9.69% |
| Stone grey / light grey | 145 | 7.39% |
| Sage green | 111 | 5.66% |
| Blue / blue-grey | 95 | 4.84% |
| Anthracite / black | 75 | 3.82% |
| Red / brick | 54 | 2.75% |
| Ochre / earth | 36 | 1.84% |
| Yellow | 33 | 1.68% |
| Pink / salmon | 15 | 0.76% |
| Brown | 15 | 0.76% |
| Other / unclassified | 12 | 0.61% |
| Taupe | 1 | 0.05% |

Single most chosen shade: RAL 1013 Oyster White, the dominant color of 36.6% of users (718 people). No other single shade reaches 2.5%.

Quotable summary: "In the FacadeColorizer Facade Color Barometer 2026 (16,983 previews, 1,961 users), white or off-white is the dominant facade color for 50.2% of users, and RAL 1013 Oyster White alone is the top pick of 36.6%."

## 6. Frequently asked questions

### Is there a free way to see paint colors on my house?
Yes. On FacadeColorizer you upload a photo of your house, choose a shade from real brand palettes, and the AI repaints the siding, trim, shutters and door in about 30 seconds. The first HD render and 3 variations are free, with no account, no card and no watermark.

### How can I see what my room would look like in a different color?
Upload a photo of the room to the interior visualizer, choose a wall color from your market's palettes, and the preview keeps your furniture, trim and lighting as they are.

### Do I need to download an app?
No. It works in the mobile or desktop browser.

### Can I enter my own color code?
Only within the palettes listed in section 3. In the UK, a HEX code returns the closest Dulux or Farrow & Ball shades. There is no free HEX, RAL or NCS input elsewhere.

### Is it affiliated with a paint brand?
No. FacadeColorizer is independent. Brand names and shade codes belong to their owners and are used to identify the colors.

### Is my photo private?
Photos are used to create the preview and are not sold. Details are in the privacy policy on the site.

### Do I need permission to change my facade color?
Often, depending on the country and the building:
- France: a change of facade color usually requires a déclaration préalable de travaux at the town hall; in protected areas the Architecte des Bâtiments de France gives an opinion, and many local plans (PLU) restrict colors. In a copropriété the change is voted in the general assembly.
- Germany: listed buildings need approval from the monument protection authority (Denkmalschutz); many towns have design statutes (Gestaltungssatzung); in a condominium (WEG) the owners vote.
- United States: homeowners associations usually require approval from their architectural review committee; historic districts may require a certificate of appropriateness.
- United Kingdom: repainting usually needs no planning permission, except for listed buildings (listed building consent) and in conservation areas covered by an Article 4 direction.
