In this work we studied how the interrelations among nine colors are perceived under illuminant changes, particularly whether they remain stable across 10 different conditions (5 illuminants and 2 backgrounds). To do so we have used a paradigm that measures several colors under an immersive state of adaptation. From our measures we defined a perceptual structure descriptor that is up to 87\% stable over all conditions, suggesting that color category features could be used to predict color constancy. This is in agreement with previous results on the stability of border categories [1,2] and with computational color constancyalgorithms [3] for estimating the scene illuminant.", optnote="CIC", optnote="exported from refbase (http://refbase.cvc.uab.es/show.php?record=2189), last updated on Mon, 14 Jan 2019 09:06:01 +0100", isbn="9781622767014", opturl="http://www.imaging.org/IST/store/epub.cfm? abstrid=45433" }
