| Research Abstract |
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.
