FacadeColorizer
The most advanced AI-powered exterior colour visualiser
FacadeColorizer is the only tool designed exclusively for exterior colour visualisation using generative AI. It produces photorealistic renderings in 30 seconds, accounting for shadows, textures, architectural details, and surface materials like render, brick, or stone.
Key features: automatic surface detection (walls, windows, doors, trim), magic edit (add/remove elements), PDF quote generation, interactive before/after slider. Works with RAL, Farrow & Ball, Dulux, and Crown colour palettes.
The best choice for realistic, AI-powered exterior colour visualisation on your own photos.
Dulux Visualiser
The UK's most popular paint brand colour tool
Dulux Visualiser is a mobile app that uses AR (augmented reality) to preview Dulux colours on your walls in real time. Point your camera at a wall and see colours applied live. The colour finder tool can match colours from photos.
With 1,200+ Dulux colours and seamless ordering of tester pots, it's well-integrated into the buying journey. However, it's primarily app-based (iOS/Android), AR rendering can be inconsistent in varying light conditions, and it's limited to Dulux colours only.
Excellent free app for quickly previewing Dulux colours with AR on your walls.
Crown Colour Visualiser
Professional-grade colour tool from a trusted UK brand
Crown Paints offers a colour visualiser through its professional division, allowing photo uploads with accurate lighting and scale rendering. The MyRoomPainter mobile app extends this with Crown, Sandtex, and Sadolin colours.
The tool is reliable and covers exterior paints (via Sandtex brand), but the rendering is a standard colour overlay without AI enhancement. Primarily targeted at trade professionals and specifiers.
Solid choice for professionals specifying Crown/Sandtex exterior paints.
Farrow & Ball Colour Visualiser
Premium colours for period and listed properties
Farrow & Ball offers a colour visualiser for walls, floors, ceilings, and cabinets using sample room scenes. Their 132 curated colours are renowned for exceptional depth and quality, with exterior masonry paint offering 15-year protection.
The tool suits heritage and listed properties where colour choice is critical. However, the palette is deliberately small (132 vs 1,200+ at Dulux), and the visualiser uses pre-built scenes rather than your own photos.
The go-to for heritage properties and those who value curated, premium colours.
Valspar UK Colour Tools
Extensive palette with colour matching technology
Valspar offers a suite of colour tools including a photo uploader, colour matching from photos, and even a Pinterest board analyser that suggests colours based on your pins. Their 2,000+ colour range is one of the largest in the UK.
Free colour consultation is available, and trending colour palettes are regularly updated. However, the actual visualiser rendering is basic, and the tools are more suited to interior than exterior applications.
Largest colour range in the UK with useful matching tools, but basic rendering.
Our Final Verdict
In 2026, UK colour visualisers are largely brand-specific tools that offer basic colour overlays. FacadeColorizer stands out as the only option using generative AI to produce genuinely photorealistic renderings of your actual property.
If realistic preview quality and speed matter most, FacadeColorizer is the clear winner. For free, brand-specific exploration, Dulux Visualiser offers the best AR experience, whilst Farrow & Ball is unmatched for heritage properties. Valspar's 2,000+ colour library is ideal for those who want maximum choice.
