- The aim of the present study was to investigate color discrimination, color naming and color preference in a random sample of 80-year-old men and women. Knowledge of color perception in old age can be of value when using color contrast, cues and codes in the environment to promote orientation and function. The color naming test indicated that the colors white, black, yellow, red, blue and green promoted recognition to the highest degree among all subjects. A gender-related difference, in favor of women, occurred in naming five of the mixed colors. Women also used more varied color names than men. Color discrimination was easier in the red and yellow area than in the blue and green area. This result correlates positively with visual function on far sight, and negatively with diagnosis of a cataract. The preference order for seven colors put blue, green and red at the top, and brown at the bottom, hence agreeing with earlier studies, and indicating that the preference order for colors remains relatively stable also in old age. This result should be considered when designing environments for old people. PMID: 10476313 [PubMed - indexed for MEDLINE]

- OBJECTIVE: To study the ability of colour naming, colour discrimination and colour preference in Alzheimer's disease (AD). DESIGN: Descriptive, consecutive sample. PARTICIPANTS: Fifty subjects >65 years with AD. INTERVENTIONS: Testing colour discrimination, colour naming and colour preferences. MAIN OUTCOME MEASURES: Ability to detect colour differences in the yellow, red, blue and green areas, ability to assign a name to 22 colour samples, ability to rank seven colours in order of preference. MAIN RESULTS: Discrimination ability was significantly better in the yellow and red area and for lightness variations. Cognitive decline had a significant impact on naming mixed colours and using elaborate colour names. Severity of dementia did not affect the preference rank order of colours. CONCLUSIONS: Ability to discriminate is affected in AD, with most errors in the blue and green area. Naming colours shows a cognitive decline. Preferences for colour are stable despite the disease.

- The proportion of elderly people in western societies is on the increase. At the same time, demands are being heard for improvements in the quality of health care, including the design of the physical environment. The aim of this study was to call attention to some aspects of colour and the possibilities of using it as an orientational aid for institutionalized demented patients and thereby enhance the quality of their care. A pilot study was carried out to establish whether patients with Alzheimer's disease are different from non-demented patients regarding certain aspects of colour perception. Twelve hospitalized patients with Alzheimer's disease were compared with a matched control group of non-demented patients regarding colour naming, colour discrimination and colour preference. No significant differences were found between the groups. In an additional experiment to test short-term memory it was found that the patients with Alzheimer's disease gained substantial help from colour cues. It is concluded that colour should be taken into account in the designing of the health care environment, particularly geriatric wards. PMID: 7777750 [PubMed - indexed for MEDLINE]
