采用分光测色计对我国100种实木地板树种的表面材色参数进行测量,研究这些参数的色空间分布特征,结果表明:各项材色参数频率分布基本上接近正态分布规律。在CIE(1976)L*a*b*色空间中,主要分布范围是米制明度L*=41.01~69.14,米制色度指数a*=6.04~17.05,米制色度指数b*=14.15~28.98,色饱和度C*=16.24~35.24,色调角Ag*=48.83~74.34;在孟塞尔系统中,主要分布范围是明度V=2.95~5.77,色饱和度C=6.04~14.24范围内,色相H在0YR~2.5Y,大多数都在YR色域之内。
The surface color parameters of 100 tree species in China were measured by spectrophotometer. The color space distribution characteristics of these parameters were studied. The results showed that the frequency distribution of each color parameter was close to normal distribution. In the CIE (1976) L * a * b * color space, the main distribution range is the metric lightness L * = 41.01-69.14, the chromaticity index a * = 6.04-17.05, the colorimetric index b * = 14.15-28.98, The color saturation is C * = 16.24 ~ 35.24 and the hue angle is Ag * = 48.83 ~ 74.34. In Munsell system, the main distribution ranges are the brightness V = 2.95 ~ 5.77 and the color saturation C = 6.04 ~ 14.24. The hue H In 0YR ~ 2.5Y, most of them are within the YR color gamut.
