Color memory matching: Time effect and other factors

The methods of simultaneous and successive, or memory, color matching have been compared for 10 color reference samples distributed in two groups each performed by 50 observers (25 men and 25 women). Our results, obtained with a total of two hundred Munsell color chips arrayed on ten gray cardboard panels, indicate that: (a) while by simultaneous matching the mean color differences obtained are, in most cases, lower than 1 CIELAB unit, those obtained by memory are generally higher; (b) the worst remembered colors are yellow, light green, blue, and pink, and the best remembered color is orange; (c) the influence of the delay time (15 s, 15 min, and 24 h) is significant for the remembered mean color (p < 0.03); (d) we find significant men-women differences for the remembered mean color (p < 0.05). © 1998 John Wiley & Sons, Inc.

Familiar objects and memory color

Memory color for a set of eight different familiar objects has been investigated. Our results obtained with one hundred observers, eighty color samples of NCS, and two illuminants indicate that: (a) the shifts that are produced in the dominant wavelength with memory depend on the familiar object considered; (b) colorimetric purity, as a measure of saturation, of the remembered objects is not the same as that of the familiar objects; (c) in the SVF representation space, with illuminant D65 and regardless of experience in color matching of the observer, the color that was best remembered was purple aubergine and the worst remembered was brown chestnut. With the illuminant A, red tomato was the best remembered color and yellow lemon the worst. © 1998 John Wiley & Sons, Inc. Col Res Appl, 23: 416–427, 1998     

A comparative study of the emotional assessment of automotive exterior colors in Asia

This article compares color assessments of automotive exteriors at four locations in China, Thailand and Japan. This study employed painted panels of twelve colors, thirty sensory words and fifteen pairs of emotion variables. It also used reference figures of nine cars that included four styling categories, namely sedans, compacts, sport utility vehicles and sports cars. The results of like-dislike tests revealed that basic automotive exterior colors, such as black, white and red, were highly preferred across locations. However, geographical differences are apparent in the preference for some non-basic colors. To elucidate these geographical differences, a Chi-square test and principal component analysis were performed on the data on emotion variables. The results revealed both similarities and differences in color preferences among the four locations. Color preferences were similar in Hong Kong and Shanghai when simply evaluated by color samples. However, similar preferences for automotive exterior colors were observed in Hong Kong, Kyoto and Bangkok, but not in Shanghai. These results suggest that there is fluctuation in the emotion evoked by a color when the color is considered in the context of automotive exteriors. Therefore, this study indicates that automotive sales can be secured in the global marketplace by creating a single palette of exterior colors based on similar color preferences across countries. However, these results also indicate that preparing market-specific automotive-color line-ups can be an effective marketing strategy.     

Why only blue in the traditional architecture of western Himalaya,India?

The local environment defines the traditional designs and color of buildings in remote wilderness areas. Color, an integral element of the traditional architecture, is related to the culture, experience, perception, and beliefs, which forms a part of the traditional knowledge of the user. Some ethnic groups have been using some specific color patterns in their houses for generations, which have been carried forward in their traditions and customs. Recognizing this, a study to document the color preference and motivations for the preference of specific colors by an ethnic community residing in the interior valleys of western Himalaya was conducted. By group discussions, 13 indicators, which further merged into five motivation categories, were identified. Semistructured interviews (n = 159) were conducted to assess the perception of selected ethnic groups toward color preference. This study reveals that color preference in architecture is influenced by psychological and sociocultural reasons that vary with gender and age classes.     

Does interior color contrast enhance spatial memory?

This study investigated the effect of contrast in neutral-, warm-, and cool-colored spaces on spatial memory. Spatial memory was measured in terms of architectural scale and recollection of architectural elements and furniture. Participants (N = 114) viewed a short virtual simulation video of a residential studio and were asked to sketch a map of the architectural elements on distributed grid paper. Spatial memory was measured in terms of scale, and item recall rate. Contrast and hue had no significant effect on the memorization of proportional scale. However, high-contrast schemes allowed for a significantly higher recollection of architectural elements than low-contrast schemes. In comparing the effect of hues, a significant difference was seen in recalling detailed furniture and lighting items. Participants reported significantly better spatial memory of neutral and warm color schemes than of cool color schemes. There was no interaction effect between contrast and hue in the color combinations. These results can be applied in the design of color schemes for architectural spaces requiring enhanced spatial cognition and memory.
