问你个问题，在一本教科书上看到了一段话：
“It is important to keep in mind taht having three specific primary color wavelengths for the purpose standardization dose not mean that these three fixed RGB components acting alone can generate all spectrum colors. Use of word primary has been widely misinterpreted to mean that three standard primaries, when mixed in various intensity proportions, can produce all visible colors. ……this interpretation is not correct unless the wavelenth also is allowed to vary, in which case we would no longer have three fixed, standard primary colors”
这句话理解得不透彻，你有什么高见？在这段话之前说到国际照明委员会定义了三种标准原色的波长。红色700nm，蓝色435.8nm，绿色546.1。
