I have heard this recommended by others but never looked into the research. Anecdotally I have found that very elderly patients/people with dementia react positively to colorful things. However, a casual googling of this revealed that “colorful stuff for dementia patients” is more of a “folk wisdom” being passed around as opposed to something with a rigorous backing (there are articles about the phenomenon like this: https://www.enablingenvironments.com.au/colour-perception-and-contrast.html). My theory of why it might be good is a) more sensory stimulation which keeps the brain active, especially in more severe cases b) helps them distinguish and remember the locations of different items more easily c) association with positive emotions (bright → happy) d) as eyesight declines, brighter colors are required to elicit the same amount of attention / visual stimulation
