“…Another paper often cited as providing evidence of the increased saturation for remembered color is [10]. In this study participants' recollections of the color of 8 common fruit and vegetables were assessed under two illuminants and compared to measurements taken from real examples of the produce.…”

Bias effects of short- and long-term color memory for unique objects

Are objects remembered with a more saturated color? Some of the evidence supporting this statement comes from research using 'memory colors' -the typical colors of particular objects, for example the green of grass. The problematic aspect of these findings is that many different exemplars exist, some of which might exhibit a higher saturation than the one measured by the experimenter. Here we avoid this problem by using unique personal items and comparing long-and short-term color memory matches (in Hue, Value and Chroma) with those obtained with the object present. Our results, on average, confirm that objects are remembered as more saturated than they are. © 201X Optical Society of AmericaOCIS codes : (330.0330) Vision, color, and visual optics; (330.1690) Color; (330.1720 1.IntroductionIn our everyday life color is a property strongly associated with objects and we have all heard and maybe even seen with our mind's eye the "red rose" of Robert Burn's poem or the "green grass of home" sung by Tom Jones. This idea of linking certain objects with a defined color was formalized by Hering and Katz in the early 20 century, as discussed in [1,2]. Subsequently Koffka [3] and others put forward the specific hypothesis that colors are remembered more saturated, in line with the Gestalt hypothesis of change towards better or the ideal; sometimes identified as a 'positive time error ' [4]. A modern formulation of this can now be found as a statement of fact in some image processing [5] and photography books [6]. However in more than 80 years of research into color and memory the evidence to support this has been inconclusive at best.Hanawalt & Post [2] report 4 studies using different methods to explicitly test for an increase in saturation of remembered colors. They used abstract color stimuli, different task and timings; under none of their tested conditions they find that remembered colors are more saturated.In Newhall et al. [7] the main experiment is a study using colored lights (2 deg visual field) presented against a neutral background where the authors compared simultaneous color matches with successive. The latter being the memory task, where after a gap of 5 sec. participants were asked to set the colorimeter to the color that had been previously presented also for 5 sec. A comparison between the matches in the simultaneous and the successive condition indicates a consistent increase in Munsell Chroma (and Value to a lesser extent) for the memory matches. In this paper they also describe an older study (their Supplementary Experiment 3) in which participants are asked to select Munsell samples that best represent the recalled colors of a series of unseen objects of highly diagnostic color (brick, sand, grass and dry grass, skin, concrete, pine trees and weathered wood). For some of these objects the memory matches seem to be of higher Munsell Chroma and Value than the 'standards' they compare them to. This latter experiment was recreated by Bartleson [8] using essentially the same methods and arriving at s...

“…Siple and Springer [6] confirmed the tendency for saturation increase, but reported quite accurate agreement for brightness and hue. In a study by Pérez-Carpinell, de Fez, Baldoví and Soriano [7] memory saturation only increased for high purity objects, while it decreased or remained the same for midrange or low purity objects. They also reported unsystematic hue shifts specific to the familiar object investigated.…”

Abstract:The effect of cross-regional or cross-cultural differences on color appearance ratings and memory colors of familiar objects was investigated in seven different countries/regions -Belgium, Hungary, Brazil, Colombia, Taiwan, China and Iran. In each region the familiar objects were presented on a calibrated monitor in over 100 different colors to a test panel of observers that were asked to rate the similarity of the presented object color with respect to what they thought the object looks like in reality (memory color). For each object and region the mean observer ratings were modeled by a bivariate Gaussian function. A statistical analysis showed significant (p < 0.001) differences between the region average observers and the global average observer obtained by pooling the data from all regions. However, the effect size of geographical region or culture was found to be small. In fact, the differences between the region average observers and the global average observer were found to of the same magnitude or smaller than the typical within region inter-observer variability. Thus, although statistical differences in color appearance ratings and memory between regions were found, regional impact is not likely to be of practical importance.

“…When an object of a well-known color is illuminated in such a way that the color that it offers is quite different from the color that identifies it, the perception of its color is influenced by the color memory of the object. [1][2][3][4][5][6][7] We do not need to take this into account when we work with color chips. [8][9][10][11] Hamwi and Landis, 12 Bumham and Clark, 13 Newhall et al, 8 Nilsson and Nelson,14 etc., find that successive matching shows a greater variability than simultaneous matching.…”

The methods of simultaneous and successive color matching have been studied for a set of seven color reference samples by 15 protanomalous and 21 deuteranomalous trichromat subjects. From comparison between both populations and a group of 25 trichromat normal ones, investigated previously under similar experimental conditions [J. Pérez-Carpinell et al. Color memory matching: time effect and other factors. Color Res Appl 1998;23:234 -247], we can deduce the following. (a) For anomalous trichromat populations, as with a normal one, we find significant differences between simultaneous and successive color matching, p Ͻ 0.05. (b) If we consider the average of all the colors, we find that, while for anomalous populations there is no influence of delay time on the remembered mean color, for normal observers there is a significant difference between 15 s and the rest of the times, p Ͻ 0.03. (c) If we consider the mean of all delay times, we find that, while normal trichromat observers do not remember yellow as well as dark orange, dark blue, and violet, in anomalous populations this happens only between yellow and dark orange. (d) By memory, we find for some reference tests a correlation between the behavior in some of the components of color difference and the observers' type of color vision anomaly.
