要混合顔色既問題。。。。

for RGB 100%,its a physics's combination,but physics's concept,Black means occured when NO ANY COLORS REFLECTED TO OUR EYES,SO BLACK IS NOT A COLOR ACTUALLY,so in the electromagnetic spectrum.will not have the black color in the spectrum,

when you can't combine with any difference color to mix to black or white,
than black and white will not present in the color spectrum,so therefore,black and white will not have the wavelength.

光源三原色無法混合黑色
顔料三原色無法混合白色

1. 世上沒有黑色的光, 因為沒有光才叫黑色

2. 顏料本身吸光, 不同顏色的顏料吸不同顏色的光 (只有白色顏料例外), 本身吸光的顏料不可能變得不吸收任何光
換言之, 某種三原色的顏料加上另一種三原色的顏料, 只會吸多其他光, 而不會反射更多的光
