Light and color as tools of pedestrian navigation in the urban environment under the influence of climatic factors (the case of Novosibirsk)

This publication continues the research work entitled «Hierarchy of Color-Light Contrasts in the Urban Navigation System» and focuses on identifying the features of landmark perception under the influence of climatic factors. The spatial organization of the contemporary city — characterized by a high level of visual saturation, complex morphology, and functional layering — becomes especially sensitive to a decline in navigation efficiency under the influence of natural and climatic conditions. In situations of reduced visibility caused by atmospheric precipitation, fog, or diurnal light dynamics, traditional graphic navigation elements lose their informativeness and perceptual accessibility. The article proposes a conceptual scheme of color-light navigation in the context of natural and climatic influences. Theoretical assumptions are illustrated by the example of Novosibirsk — a large Siberian metropolis with a sharply continental climate, marked by a wide range of weather conditions, abundant precipitation, prolonged frosts, and short daylight hours — making it a suitable model for assessing the navigational potential of the urban environment under climatic constraints.
