Effects of surface material perception on color appearance

我们发现，金、银和铜的感知程度，以及产生金、银和铜的色度区域的大小随着感知光泽度的增加而增加，但随着亮度的增加而减少。这些结果表明，人类视觉系统利用表面的光泽度和亮度来感知金、银或铜。我们还发现，对金、银、铜的感知与对金属的感知密切相关。当感知金、银或铜时，也会获得金属感知。这些结果证实了金属感知是金、银、铜感知的必要条件。此外，我们还讨论了材料与颜色感知之间的关系机制，以解释这些结果。

Ｗ e found that the degree of gold, silver and copper perception, and the size of chromaticity regions to yield gold, silver and copper increased with the perceived glossiness, but reduced with the lightness. These results indicate that the human visual system uses glossiness and lightness of the surface to perceive gold, silver or copper. We also found that gold, silver and copper perception strongly correlated with metallic perception. When gold, silver or copper was perceived, metallic perception was also obtained. These results confirmed that metallic perception is necessary for gold silver and copper perception. Furthermore, we discussed a mechanism of relationship between material and color perception that could explain the results.
