Tips for colour selection
- Colour awakens emotional responses related to past experiences and cultural background.
- Colour can be used to increase and reduce visibility.
- Colour contrast and good lighting help people’s navigation, orientation, mobility, independence and involvement.
- Too many colours together can be distracting.
- Older people are best able to discriminate strong colours at the warm end of the spectrum.
- Colours with a high degree of brightness, such as yellow, are highly visible.
- Colours such as peach, coral and soft apricot tones flatter skin tones and add warmth to any setting.
- Pastel blues and lavenders are hard for older people to see and often look grey.
- People with colour vision issues are less sensitive to colours on either end of the colour spectrum. Reds and blues will look darker.
- As colour preferences are personal, giving people the chance to personalise private spaces is important.
Effective colour contrasts
Older people need about three times as much contrast as younger people to find objects. Choose colours of major contrast.
Combine light colours from the middle of the spectrum, for example, yellow or green, with dark colours from either end of the spectrum, for example, red or blue, to produce the most effective contrasts. Do not combine dark green against bright red, yellow against white, blue against green, or lavender against pink.
Camouflaging with colour
Colour can be used to make objects more visible, or it can hide or camouflage them. Choosing background colours similar to the colour of objects in the foreground can make objects invisible to a person with dementia.
Colour and lighting
Lighting helps in effective colour contrast. The amount of natural daylight should affect the choice of colours as the colour is visibly changed by different light sources. Carpet, wall colour, fabrics, furniture and accessories look much brighter in direct daylight than under artificial light. Test your colour choices in day and evening light where they are to be used.
Colour rendering means how true colours look under a given light source. How colour looks under daylight is seen as true and accurate. Light sources are compared to daylight through a Colour Rendering Index. The Colour Rendering Index for lamps uses 100 as the number for light most closely resembling typical daylight. A bulb with a number of 80 or higher can provide a reasonably accurate colour rendering. The temperature of the light source is also a measure of colour rendering, with degrees Kelvin being the standard measure. The higher the temperature, the cooler the light and the closer to daylight. The recommended light rating that simulates daylight conditions or incandescent lighting is 3000–3500 degrees Kelvin.
Colour and wayfinding
Use of colour in wayfinding is most important. Using colour and creating colour contrasts helps people to move about more confidently, reducing confusion and agitation.
Understanding what you do well in your facility and identifying where you could improve is a good start to developing strategies for the use of colour.
- Think about age, gender, cultural background, religious or spiritual needs and socio-economic circumstances of people with dementia and families when selecting colours.
- Create up to five colour swatches from which new residents and families can choose their preferred colour scheme for bedrooms, ideally including fabric, wallpaper and paint samples.
- Think about staff preferences for colours in staff areas.
- Select the colour of more expensive items, such as furniture and furnishings before selecting paint, which is less expensive and easier to change.
- Increase colour contrast between furniture and walls to increase visibility.
- Provide effective colour contrasting throughout a facility, unless wanting to minimise visibility.
- Select colours that allow for ageing vision and visual ability.
- Combine light colours, such as yellow or green, with dark colours, such as red or blue, to produce the most effective contrasts.
- Avoid dark green against bright red, yellow against white, blue against green, and lavender against pink.
- Test colour samples under proposed lighting conditions to verify how they will appear.
- Provide good lighting to enhance your colour scheme.
Colour in dining areas
- Add colour contrasting edges to tables to increase visibility.
- Use placemats that colour contrast with table tops, plates and utensils.
- Select cups and plates with colour contrasting rims or edges to improve visibility.
- Contrast plates, utensils and containers in colour or brightness against table cloths.
- Encourage skilful use of colour on white plates to make food easier to see and eat.
- Use clear, high colour contrast print of appropriate size on menu cards and place cards where used.
Colour in bathrooms
- Colour contrast toilet seats with toilet bowls and floor.
- Use warm peach coloured tones that flatter skin tones.
Colour combinations for effective colour contrasts are light colours against black, dark colours against white, light yellow against dark blue, light green against dark red.
