If you are weighing up the Crown MyRoomPainter app against FacadeColorizer for your next UK paint decision, you are comparing a Crown-branded interior visualiser against a multi-brand AI tool that handles both interiors and exteriors. Crown is one of the UK's most established paint manufacturers, with a Lancashire factory in Darwen and a strong following among British decorators. MyRoomPainter is its free in-house visualiser, focused on interior rooms and the Crown palette. FacadeColorizer is a younger, browser-based AI visualiser built on Google Gemini that supports Farrow & Ball, Little Greene, Crown, Dulux Heritage, RAL and BS 4800.
As a paint and colour consultant working with UK homeowners, period property buyers and decorators, I have used both tools on real jobs. Crown MyRoomPainter is the right tool when you are committed to Crown and you want a quick interior preview. FacadeColorizer is the right tool when you want to compare brands, render an exterior facade, organise a HD before-and-after image for a quotation, or work on a conservation area project. Below you will find the quick comparison table, a detailed breakdown of both tools, four UK use-case verdicts, pricing in pounds, and a frequently asked questions section that addresses listed buildings and the heritage palette.

Crown MyRoomPainter in detail
Crown Paints, headquartered in Darwen, Lancashire, has been one of the UK's mainstream paint brands since 1814 and runs a strong network of 120 Crown Decorating Centres across Britain. Its in-house visualiser, MyRoomPainter, is a free interior colour preview tool available on iOS, Android and the Crown website. It lets users upload a photo of a room, mask the wall area, and apply Crown shades on top. It is the natural starting point for any homeowner already committed to Crown.
Strengths
- Crown brand authority in the UK: Crown is one of the country's most recognised paint brands, manufactured in Lancashire, stocked at B&Q, Wickes, Homebase and 120 Crown Decorating Centres. The shades you preview match exactly the tins you can buy on the high street.
- Decent interior coverage: the tool handles standard interior walls reasonably well in good lighting, with a simple workflow that is easy for non-technical users to organise on a Saturday afternoon.
- Free with no signup: download or open in browser, upload, preview. No paywall, no subscription, no email gate.
- Mobile and web: available on iOS, Android and through the Crown website, so users can pick the device that suits their workflow.
Weaknesses
- Crown-locked palette: you cannot test a Farrow & Ball Hague Blue, a Little Greene Sage Green or a Dulux Heritage shade. For a UK homeowner who wants to compare brands, that is a hard ceiling.
- Interior focused, weak on exterior: the tool is built for indoor walls, not facades, render or masonry. Crown sells exterior products (Crown Trade Sandtex, Crown Weatherproof Smooth Masonry) but MyRoomPainter does not handle the exterior visualisation those products call for.
- Simpler UX than AI tools: the patch overlay struggles with textured surfaces, lining paper, dado rail, coving and complex room geometry. Output is a low-resolution web preview, not a printable HD image.
Best for the UK profile
A homeowner painting a bedroom, living room or kitchen with Crown, on a flat interior wall, in good daylight, who wants a quick yes-or-no on a single shade. For that profile, Crown MyRoomPainter is a sensible free first step.
FacadeColorizer in detail
FacadeColorizer is an AI-powered colour visualiser built on the Google Gemini image generation engine. It runs in any browser, works on photos rather than live AR, and returns a high-resolution rendered image of your house or room in the colour you picked. It is multi-market (UK, FR, US, DE) and not UK-specific, which is both a strength (multi-brand palette) and a limitation (less tailored UK marketing).
Strengths
- AI Gemini generative engine: the AI re-renders the surface, including texture, shadow direction, render bumps and brick mortar lines. This is a step change above patch overlays for photorealism.
- Pack Colour at £8.90: the paid tier unlocks 3 additional HD images without watermark, paid once, no subscription, immediate activation. The free tier still gives 1 HD plus 3 watermarked tries.
- Exterior and interior in one tool: facade, render, masonry, woodwork, front doors, sash windows on one side; walls, skirting, coving, feature walls on the other. One engine handles both.
- Multi-brand palette including Farrow & Ball and Little Greene, plus Crown, Dulux Heritage, Mylands, RAL and BS 4800. The full UK heritage palette is supported, which is essential for period properties and conservation area work.
Weaknesses
- Young brand: launched in 2024, so brand recognition in the UK is far below Crown or Dulux. Homeowners may not have heard of it on the high street.
- Not UK-specific: the tool serves multiple markets, so the marketing copy is not as tightly tailored to UK terminology and conventions as a UK-only product would be. The functionality is the same; the brand voice is multi-market.
Best for the UK profile
A Victorian or Edwardian period property owner choosing between Farrow & Ball and Little Greene, a decorator preparing a client presentation with HD before-and-after images, a heritage architect submitting visuals with a planning application, or anyone repainting an exterior facade.

UK use cases: which tool wins for which profile
Four typical UK paint decisions, four honest verdicts based on hands-on testing.
Period property owner (Victorian, Edwardian, Georgian)
If you own a period property in Bath, Edinburgh, Brighton, Cheltenham or any UK historic high street, you are almost certainly choosing between heritage palettes: Farrow & Ball, Little Greene, Mylands, Edward Bulmer or Dulux Heritage. Crown MyRoomPainter cannot show you a Farrow & Ball or Little Greene colour, so it loses on the very first decision. FacadeColorizer wins clearly here, with the full heritage palette and the texture handling needed for original lime plaster, lath and plaster, or original sash window reveals. Verdict: FacadeColorizer.
Painter and decorator preparing a quote
A professional decorator visiting a UK home for a quote needs a HD before-and-after image they can email to the client, attach to a quotation, or save in their portfolio. Crown MyRoomPainter only outputs a low-resolution web preview, not a printable image. FacadeColorizer's Pack Colour at £8.90 unlocks 3 HD downloads per project, easily covered in a single quote. Verdict: FacadeColorizer.
Heritage architect or planning consultant
For listed buildings and homes within conservation areas, local planning authorities increasingly request a visual indication of the proposed colour change, especially in Bath, the Cotswolds, the Lake District and central London boroughs. A web screenshot is rarely accepted, a printable HD render is. FacadeColorizer outputs a high-resolution image suitable for inclusion in a planning portal submission. Crown MyRoomPainter does not, and is interior only. Verdict: FacadeColorizer.
Homeowner testing a single Crown shade in a flat-wall bedroom
A homeowner who has already decided on Crown and just wants to compare two of its shades on a smooth living room wall in good daylight. Quick, free, mobile, no signup. Crown MyRoomPainter is the right tool here, the patch overlay does the job and you can buy the tin at any Crown Decorating Centre tomorrow. Verdict: Crown MyRoomPainter.
UK pricing comparison
Both tools have a free tier. The paid tier on FacadeColorizer is positioned as a one-time, no-subscription unlock for HD downloads.
| Tier | Crown MyRoomPainter | FacadeColorizer |
|---|---|---|
| Free | Unlimited interior previews, screenshots only | 1 HD download plus 3 watermarked tries |
| Paid (one-time) | Not available | Pack Colour £8.90 (3 extra HD, no watermark) |
| Subscription | No | No |
| Activation | App download or browser | Secure payment, immediate activation, no commitment |
For context, a single 2.5 L tin of Crown Matt is around £22 in the UK, and a Farrow & Ball Estate Emulsion 2.5 L is around £56. Spending £8.90 once on a Pack Colour to organise the right colour decision is fractional compared with the cost of repainting an entire room because the shade was wrong.
Honest verdict
Both tools are good. They are not direct competitors so much as tools optimised for different jobs. Crown MyRoomPainter remains a sensible free first-pass tool for anyone settled on Crown who wants a quick interior preview. It is free, well-supported, and backed by a respected UK manufacturing brand based in Lancashire. There is no shame in using it for what it does well.
FacadeColorizer wins for the harder, higher-stakes UK paint decisions: period property heritage palettes, exterior facades, conservation areas, listed buildings, decorator client presentations and any project where you want HD output and the ability to compare brands. The Pack Colour at £8.90 is the price of two tester pots, paid once, no subscription, no commitment, and unlocks 3 HD images without watermark.
If you are unsure, the pragmatic answer is: start with FacadeColorizer's free tier (1 HD image plus 3 watermarked tries), see whether the AI Gemini render quality matches your expectations on your specific photo, and only step up to the Pack Colour if you need additional HD outputs. For a single Crown shade in a flat bedroom, stick with Crown MyRoomPainter.

Frequently asked questions
Can Crown MyRoomPainter show Farrow & Ball or Little Greene colours?
No. Crown MyRoomPainter is locked to the Crown palette of around 1,100 shades plus the Crown Period Collection. To preview Farrow & Ball, Little Greene, Mylands or Dulux Heritage shades on your walls or facade, you need a multi-brand visualiser such as FacadeColorizer, which supports the major UK heritage palettes alongside Crown, RAL and BS 4800.
Is FacadeColorizer free?
Yes, the free tier gives you 1 HD download plus 3 watermarked tries. To unlock 3 additional HD images without watermark you can buy the Pack Colour for £8.90 once, no subscription, secure payment, immediate activation, no commitment. There is no recurring billing.
Does Crown MyRoomPainter work on a facade or exterior?
No. Crown MyRoomPainter is interior focused. Crown sells exterior products including Sandtex and Crown Weatherproof Smooth Masonry, but its in-house visualiser is not built for facade, render or masonry rendering. For exterior projects you need a tool such as FacadeColorizer that handles facades, brick, render, sash windows and front doors as separate zones.
Can I use a colour visualiser for a conservation area or listed building application?
Yes. Many UK local planning authorities (Bath, the Cotswolds, central London boroughs, Edinburgh) request a visual indication of any proposed colour change for buildings within a conservation area or for a listed building. FacadeColorizer outputs a high-resolution image suitable for inclusion in your planning portal submission. Crown MyRoomPainter only outputs a low-resolution web preview, rarely accepted as planning evidence.
Which is best for a Victorian terrace in Brighton or a Georgian townhouse in Bath?
FacadeColorizer, because period properties almost always involve heritage colour palettes (Farrow & Ball, Little Greene, Mylands, Edward Bulmer) that Crown MyRoomPainter cannot display. It also handles original architectural features (sash windows, cornice, dado rail, lath and plaster textures) more realistically thanks to the AI Gemini render engine, and supports both interior and exterior in the same tool.
Should a UK painter and decorator switch from Crown MyRoomPainter to FacadeColorizer?
You do not need to switch. Use both. Use Crown MyRoomPainter for a quick on-site interior preview when the client is committed to Crown. Use FacadeColorizer when you want to organise a HD before-and-after image to attach to a quotation, when the client is comparing brands, when the project involves a facade, or when working on a period property. Many UK decorators in 2026 use the two side by side.
