Descripción
The natural environment has shaped our visual system. An important tool for the study of color vision is to know the chromatic statistics of the environment. However, there is a geographical bias regarding the availability of the data. Here, we present spectral measurements of more than 500 samples of natural objects obtained in the southern cone of South America. The object collection was carried out in the north of Argentina (-26.84°, 65.23°), between the months of June 2023 and February 2024. The samples were categorized into flowers (N = 108), leaves (N = 114), stones (N = 65), barks (N = 20), fruits (N = 31), non-edible fruits (N = 14), vegetables (N = 9), beetles (N = 8, total samples = 9), butterflies (N = 14, total samples = 30), birds (N = 35, total samples = 105). Spectral measurements of their reflectance properties were carried out in a calibrated and controlled light booth using a spectroradiometer (Photoresearch Inc.) that provides information from 380 to 1068 nm. For the analysis, we computed the cone excitations of the objects when placed under the equal energy white light and represented the data in the MacLeod and Boynton chromaticity diagram. For each category, we obtained the median of the data distributions along the L/(L+M) and S/(L+M) axes of the diagram, which roughly correspond to red-green and purple-lime directions, respectively. In the L/(L+M) domain, the highest median value was found for flowers and the lowest was for leaves. In the S/(L+M) domain, the highest median was for flowers and the lowest was for fruits. Also, we found a relatively large variety of colors for different species of flowers, butterflies, and birds, while barks, stones, and leaves colors are relatively similar between species. This database will be useful to study the particularities of the natural environment in South America, a major biodiverse region, and to better understand the evolution of color perception of different visual systems throughout the world.
