The first insights into the nature of color vision came from Isaac Newton. In his room at Cambridge University, he placed a prism so that sunlight shining through a hole in the shutter of his window entered the prism. He observed that the sunlight became transformed by its passage through the prism into a spectrum of colors. He also noted that the sunlight could be reconstituted by recombining the spectral colors. Newton concluded that sunlight is made up of each of the spectral colors. Later work showed that these spectral colors differed in wavelength thus demonstrating for the first time the link between wavelength and color. However, it was clear to Newton that ... the rays ... are not colored, in other words, color is a perceptual rather than physical phenomenon.
T对颜色最早提出见解的是牛顿（Isaac Newton）. 在他剑桥大学（Cambridge University）的房间里，他放置了一个棱镜，然后让阳光透过他窗户的一个小洞进入棱镜。 他观察到，太阳光通过棱镜转变成了各种颜色的光谱。他同时观察到多种颜色的光组合在一起成为白光。牛顿得出结论白光是由不同颜色的光组成的.后来的研究表明，这些光谱颜色不同的波长，从而证明了第一次波长和颜色之间的联系。然而，牛顿清晰的知道 ... 光线 ... 不是彩色的, 换句话说, 颜色是感性的而非理性的
