Why bananas look yellow: The dominant hue of object colours. Witzel, C. & Dewis, H. Vision Research, 200:108078, November, 2022. ![Why bananas look yellow: The dominant hue of object colours [link]](https://bibbase.org/img/filetypes/link.svg "link")
Paper doi abstract bibtex In this study, we propose a new approach to the perceptual representation of object colours. Three-dimensional objects have a polychromatic colour distribution. Yet, human observers abstract from the variation along the three perceptual colour dimensions when describing objects, such as when we say, “a banana is yellow”. We propose that the perceived object colour is determined by the dominant hue. The dominant hue corresponds to the first principal component of an object’s chromaticities. Across three experiments, we show for a sample of objects that the chromatic variation away from the dominant hue is almost completely neglected by human observers under non-laboratory viewing conditions. This is partly due to the low visibility of this variation, and partly to attentional change blindness. These findings reveal the potential role of dominant hue in the perception of object colours. Dominant hue may enable us to determine the most representative colours of objects because perceived object colours tend to be maximally bright and saturated. The present findings also imply that we can simplify the colour distributions of objects by projecting them onto their dominant hue. This may be useful for computational applications.
