摘　　要：选取不同颗粒度的岩肌、白翠末等矿物颜料,采用简化的Mie散射理论,研究矿物颜料颗粒度对色彩的影响。研究结果表明,随着颜料颗粒度的减小,白翠末和岩肌的光谱反射率明显增加,颜色的明度值也均随之增加,而其颜色饱和度随之降低,且对于同种颜料而言,随着颗粒度的改变,颜色的色相有微小变化。Several mineral pigments such as burnt carnelian and amazonite were selected and researched. The effects of mineral pigment particle size on color were studied by using the simplified Mie scattering theory. The results show that the spectral reflectance and color brightness increase obviously with the decreasing in pigment particle size, while the color saturation decreases. For the same kind of pigment, the pigment particle size has minute effect on hue.
