W pływ koloru na ludzką podświadomość i psychikę jest tematem badań naukowców wielu dziedzin nauki - zakres wpływu barw na człowieka jest szeroki oraz złożony, a czynniki powodujące reakcje na daną barwę mają podłoże zarówno biologiczne, psychologiczne, emocjonalne, jak i kulturowe. Odwołując się do rezultatów badań na temat teorii koloru, analizie został poddany ich wpływ na odbiór obiektów architektonicznych - zarówno w zakresie oddziaływania w bliższym ich widzeniu - odbioru projektu, jak i dalszym - w ramach szerszego kontekstu czy założenia urbanistycznego. W artykule zostały przytoczone wybrane projekty holenderskiej pracowni MVRDV, wyróżniające się dużym udziałem intensywnych, jasnych i czystych barw, ze zwróceniem uwagi na znaczenie ich użycia w projektach architektonicznych, urbanistycznych, wnętrz oraz instalacji artystycznych. Rozważania teoretyczne uzupełnione są odpowiedzią jednej z wiodących architektek z rotterdamskiej pracowni - Fokke Moerel, na postawione w ramach artykułu pytania.

The influence of colour on the human subconscious and psyche is the subject of research in many fields of science - the scope of the influence of color is various, as its impact on humans is complex, including biological, psychological, emotional and cultural basis. Referring to the results of scientific research on the theory of color, the impact of the colour will be analyzed in the context of perception of architectural forms, both in small and large scale, comprising seeing it as an singular object and within a wider context as a part of urban tissue. The article cites a selection of projects by the dutch MVRDV studio, that stands out due to uncommon, astonishing use of intense, bright and pure colors, paying attention to the importance of their purpose in architectural and urban projects, interiors and artistic installations. Theoretical considerations are supplemented with the answers of one of the leading architects from the Rotterdam studio - Fokke Moerel, referring to the main issue of the article.

A human observer is able to determine the color of objects independent of the light illuminating these objects. This ability is known as color constancy. In the first stages of visual information processing, data are analyzed with respect to wavelength composition, orientation, motion, and depth. With this contribution, we investigate whether depth information can help in estimating the color of the objects. We assume that local space average color is computed in V4 through resistively coupled neurons to estimate the color of the illuminant. We show how this computational model can be extended to incorporate depth information.

Color is not a physical quantity of an object. It cannot be measured. We can only measure reflectance, i.e. the amount of light reflected for each wavelength. Nevertheless, we attach colors to the objects around us. A human observer perceives colors as being approximately constant irrespective of the illuminant which is used to illuminate the scene. Colors are a very important cue in everyday life. They can be used to recognize or distinguish different objects. Currently, we do not yet know how the brain arrives at a color constant or approximately color constant descriptor, i.e. what computational processing is actually performed by the brain. What we need is a computational description of color perception in particular and color vision in general. Only if we are able to write down a full computational theory of the visual system then we have understood how the visual system works. With this contribution, a computational model of color perception is presented. This model is much simpler compared to previous theories. It is able to compute a color constant descriptor even in the presence of spatially varying illuminants. According to this model, the cones respond approximately logarithmic to the irradiance entering the eye. Cells in V1 perform a change of the coordinate system such that colors are represented along a red-green, a blue-yellow and a black-white axis. Cells in V4 compute local space average color using a resistive grid. The resistive grid is formed by cells in V4. The left and right hemispheres are connected via the corpus callosum. A color constant descriptor which is presumably used for color based object recognition is computed by subtracting local space average color from the cone response within a rotated coordinate system.

The correctness of color vision is the essential problem in Lighting Technology, Human Computer Interaction and Computer Graphics. To answer the question about correctness of perception process the workings of the whole human vision system should be analyzed. The color information can be falsified in the perception process. In many cases it is useful for us but often does not allow obtaining information about true color in proper way. But what is really true: the measured color or our “real subjective” perception?

Percepcja barw jest jednym z podstawowych problemów techniki świetlnej, grafiki komputerowej i komunikacji człowiek-komputer. Aby odpowiedzieć na pytanie o poprawność interpretacji wrażeń barwnych, cały proces widzenia musi zostać przeanalizowany. Informacja o barwie może być fałszowana w procesie percepcji, często jest to dla nas korzystne. Powstaje jednak pytanie: na ile jest to subiektywne, czy oko jest dobrym instrumentem oceny barw?
