Colour memory for various sky, skin, and plant colours: Effect of the image context

In memory-matching techniques, the remembered colour might differ front the original colour even if the viewing situation is the same. Our aim was to point out whether these so-called memory shifts are significant in the ever yday situations of viewing photos depicting sky, skin, or plant, or viewing standalone uniform colour patches of sky, skin, or plant colours. In many cases, significant memory shifts have been found Considering only one type of object (sky or skin or plant), memory shifts turned out. to be systemati c in the sense that they were directed toward specific intervals of hue, ch roma, and lightness. This tendency was more explicit for photos than for st andalone colour patches. A method to quantify prototypical colours and thei r tolerance bounds was suggested. (C) 2001 John Wiley & Sons, Inc.
