Colour-Coded Wayfinding Systems for Dementia Care
Colour coding is one of the most powerful wayfinding tools available to care homes. This guide explains how to design and implement a colour-coded navigation system that helps residents with dementia identify zones, floors, and destinations through consistent colour cues.
Colour is one of the most intuitive wayfinding cues available. Even as dementia progresses and the ability to read text or interpret symbols declines, the ability to recognise and follow colours often remains intact well into the moderate stages. A colour-coded wayfinding system assigns distinct colours to different zones, floors, or wings of a care home, creating a visual language that residents can learn and follow without relying on literacy or complex cognitive processing. The DSDC considers colour coding a foundational element of dementia-friendly environmental design.
Designing a Colour Coding System#
An effective colour coding system uses a limited palette of highly distinguishable colours. The DSDC recommends using no more than four to six distinct zone colours, as a larger palette becomes difficult for residents with dementia to learn and differentiate. Colours should be chosen for maximum contrast with each other and with the building's neutral background colours. Warm colours such as red, orange, and yellow should be balanced against cool colours such as blue and green. Avoid using similar shades, such as two different blues, as these are easily confused by residents with reduced contrast sensitivity.
Steps to implement a colour-coded wayfinding system:
- Map the building into logical zones based on function or location (e.g., bedroom wing, communal area, garden access)
- Assign a distinct, saturated colour to each zone, ensuring colours are dissimilar from each other
- Apply the zone colour consistently to wall accents, door frames, handrails, and signage borders within that zone
- Create a colour key displayed at main entrances and communal notice boards
- Train staff to use colour references when directing residents (e.g., 'Follow the blue to the dining room')
- Coordinate signage colour with zone colour so that signs reinforce the zoning system
- Review the colour system seasonally to ensure paint, signage, and other elements remain consistent
Coordinating Signage with Colour Zones#
Signage is the primary vehicle for communicating the colour coding system to residents. Door signs, directional signs, and projecting signs should all incorporate the zone colour in a consistent way, such as a coloured border, header bar, or background panel. This creates a visual link between the sign and the wider environment. When a resident sees a blue-bordered directional sign, they learn to associate blue with that particular zone. Over time, the colour itself becomes a navigational cue that works even when the resident can no longer read the sign text.

Our dementia-friendly door signs are available in multiple colour options that can be coordinated with your zone colour scheme. From oak and walnut wood-effect finishes to bold colours including blue, green, red, purple, and brown, you can assign different sign colours to different areas of your care home to reinforce your colour-coded wayfinding system.
Pro Tip
When introducing a colour-coded system, brief families and visitors as well as staff. Families can reinforce the system by using colour references when visiting ('Your room is in the green wing'). Visitor information boards and leaflets should include the colour key. The more consistently the colour language is used by everyone in the building, the faster residents will learn it.
Evidence for Colour-Coded Wayfinding#
Research from the University of Stirling and the DSDC demonstrates that colour-coded environments reduce wayfinding errors by 25 to 40 percent in care home settings. A study published in Dementia: The International Journal of Social Research and Practice found that residents in colour-coded care homes showed significantly higher levels of independent navigation compared to those in non-coded environments. The effect was particularly pronounced for residents with moderate dementia, who retained the ability to recognise colours even when other cognitive functions had declined substantially.
Common mistake
Applying colour coding only to signage without extending it to the wider environment. For maximum effectiveness, zone colours should appear on walls, door frames, handrails, furniture accents, and even staff uniform lanyards. The more consistently a colour is applied, the stronger the association becomes for residents.
