第三四章颜色的配色定律.ppt

Color Color 可见光波长范围：380-780nm 红色(R) - 780 to 630 nm 橙色(O) - 630 to 600 nm. 黃色(Y) - 600 to 570 nm. 绿色(G) - 570 to 500 nm. 青色(C)　- 500 to 470 nm. 蓝色(B) - 470 to 420 nm. 紫色(V) - 420 to 380 nm 1、色光的三原色 (CIE)标准色光的三原色的代表波长 2、色光加色法　　按红、绿、蓝原色光的加色混合原理生成新色光的方法。　色光相加，能量增加，越加越亮。 中间色：任意两种非补色光混合产生的色光。 3、色光加色法的应用 Color 1、色料 染料 颜料 有机颜料 有机、无机颜料对比 有机颜料：着色力强、色泽鲜艳、透明性高。 无机颜料：耐热性、耐光性、遮盖力强。 染料和颜料对比 染料和颜料的应用方法 发色理论：Witt发色团学说 2、色料的三原色(三原色料） 色料三原色的性质 理想黄色料的分光光度曲线 理想品红色料的分光光度曲线 理想青色料的分光光度曲线 3、色料减色法　　当白光照射到色料上，色料从白光中减去一种或几种单色光，而呈现另一种颜色的方法称为色料减色法。　　 4、色料混合变化规律 色料减色法本质:　色料的选择性吸收，使色光能量减弱，新颜色的明亮程度降低而趋于黑暗：--色料相加，能量减弱，越加越暗。 5、色料减色法调色规律的应用 5、色料减色法的应用 色光加色法与色料减色法的对比？ Specular Reflection Light reflected at fixed angles (directional).
