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.

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.

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.

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.
