FURNITURE & INTERIORS
“Many designers are familiar with light reflectance values which essentially indicate how light or dark colour is. Even though some designers may not have lived experience with vision impairment or visual processing differences, using the Light Reflectance Value numbers makes it much easier to improve the accessibility of their colour choices. In the same way that LRVs give designers a way to identify contrast, chroma values give designers a way to identify colour intensity. Chroma is an additional consideration that denotes how saturated a colour is and therefore how intense that colour is. The greyer or desaturated a colour is, the lower the chroma value, the more intense/saturated the colour is, the higher the chroma value.
“The intensity of a colour is also dependent on the hue, with yellow tones generally having higher chroma values than blue tones for example. Choosing a colour with a lower chroma value can help to reduce the intensity of the surface which can be overstimulating for people with sensory processing differences. This doesn't entirely exclude high-chroma colours from the palette. Instead, a tailored palette for each space, taking into account surface area and surrounding materials, should be developed for review with stakeholder groups who have lived experience.
“Colour intensity can be difficult for some designers to recognise so having the chroma values to support colour choices, in the same way Light Reflectance Values assist with contrast, will hopefully improve accessibility for people who have a visual processing difference or are more sensitive to visual stimuli.
“Maria Luigia Assirelli, Director and Mental Health & Social Value Lead at Floyd Slaski Architects, was also involved in updating the colour palette for the popular Altro Whiterock Satins range.
“The introduction of new 'tonal' colours in healthcare design presents the opportunity to further refine and tailor colour palettes to the specific needs of healthcare environments. Tonal colours, which may include subtle variations within a single hue, offer a nuanced approach to colour selection that can enhance the visual interest of a space while maintaining a sense of harmony and tranquillity. By incorporating tonal colours alongside traditional low chroma hues, designers can create dynamic and visually engaging environments that still prioritise the calming effects associated with soſter tones.”
Altro has revised and updated its original Designing for Dementia CPD over the years, and also has Designing for Mental Health, both also RIBA-approved. Each seminar is approximately one hour long and is designed to fit flexibly within busy work schedules. To find out more, click here.
