使用多维缩放技术研究了对象颜色流形的维度，该技术允许将一组彩色纸张表示为欧几里得空间中的配置，其中纸张之间的距离对应于它们之间的感知差异。当纸张被均匀地照亮时，它们可以被布置为三维配置。这与物体颜色空间是三维的普遍接受的观点一致。然而，我们表明，在杂色照明下，另一个三维出现。我们称之为照明维度的物体颜色，以区别于传统的三个称为材料维度的物体颜色。
The dimensionality of the object colour manifold was studied using a multidimensional scaling technique, which allows for the representation of a set of coloured papers as a configuration in a Euclidean space where the distance between papers corresponds to the perceptual dissimilarities between them. When the papers are evenly illuminated they can be arranged as a three-dimensional configuration. This is in line with the generally accepted view that the object colour space is three-dimensional. Yet, we show that under variegated illumination another three dimensions emerge. We call them lighting dimensions of object colour in order to distinguish from the traditional three referred to as material dimensions of object colour.
