Careful consideration of architectural design is essential for developing spaces that are welcoming, futureproofed, and accessible for all. Dawn Scott of Dulux Trade discusses how colour can transform buildings and improve wellbeing for all
Inclusive design is centred on creating spaces that are accessible and usable by as many people as possible now and in the future, regardless of age, ability, or background. It not only addresses physical accessibility but also considers sensory and cognitive inclusivity across all building types, not just specialist spaces.
One of the most influential elements when designing inclusive spaces is colour. Colour affects people’s mood, behaviour, and even their ability to navigate. By carefully selecting and placing colours, architects can therefore create environments that are not only aesthetically pleasing but also supportive and inclusive.
Using colour to navigate
Everyone uses colour to help with navigation and wayfinding. Using contrasting colours across critical surfaces such as doors, walls, and ceilings makes it easier for people to move through a space. Additionally, applying contrasting colours to trim – including coving, skirting, architrave, and dado rails – can further enhance wayfinding and overall accessibility.
To ensure the best results, Building Regulations Approved Document M, Vol.2, and British Code of Practice: BS8300-2:2018 – which can help to meet the Equality Act 2010 – say that critical surfaces must have a minimum visual contrast of 30 Light Reflectance Value (LRV) points. LRV measures the percentage of visible and usable light reflected from a surface when illuminated by a light source.
Correct colour choice
When selecting colours, it is important to think about the needs of all building occupants. While any colour can be used, the specific shades and saturations should be carefully considered by specifiers for the particular project.
For example, to compensate for the ageing of the eye and subsequent colour distortion – and to support those with neurodegenerative conditions, such as Alzheimer’s or Parkinson’s – more saturated colours are key. This is because they are easier to see and differentiate, compared to muted tones.
In contrast, for neurodivergent individuals, such as those who are Autistic, the design considerations differ. Bold or more saturated colours can create overly stimulating environments that may result in some people struggling to focus or perform at their best. This also includes bright whites and shiny surfaces that create high levels of glare. It is therefore essential for more muted tones with a matt finish to be used in regularly accessed areas to help mitigate sensitivities.
However, every individual is different and will react to colours in different ways, so it is always recommended to provide a choice of environments with varying colour schemes. This will ensure a building caters to different sensory needs and enable people to choose spaces where they feel most comfortable.
Biophilic design
When selecting which specific colours to use, it is important to consider the emotions that they evoke. For example, using colours that are inspired by nature can help to create a calming and restorative atmosphere. This concept is known as biophilic design, and has been shown to reduce stress and improve mental health. It is particularly beneficial in settings like hospitals, schools, and workplaces, where reducing stress and promoting wellbeing
is crucial.
For instance, in a series of four experiments that examined the effect of the colour green on psychological functioning, it was found that exposure to green before conducting a task “facilitates creativity performance.” This is ideal for working environments and showcases the value of correct colour choice in these spaces.
However, it is important to think beyond just green when applying biophilic design principles to projects. All colours can be found in nature, think yellow sunflowers or pink cherry blossoms, so any can be used in buildings to promote wellbeing and inclusivity if the right hues are selected and paired together.
Colour tools
There are a number of colour tools available to support architects during the colour selection process. These tools can provide valuable insights into how different colours interact and look within a space.
For example, the Dulux Trade Colour Schemer tool we developed allows architects to produce colour schemes for a variety of sectors. After choosing the sector and a preferred start colour, it will show recommended shades in situ based on contrast ratios. It also offers a selection of pre-existing mood boards for giving inspiration to designers.
Inclusive design is about more than just meeting regulatory requirements; it’s about creating spaces that enhance the quality of life for all users and ensure spaces work for occupants for years to come. By understanding the impact of colour and using it thoughtfully, it is possible to create spaces that are accessible, supportive, and aesthetically pleasing.
