彩色电视及彩色涂料、印刷和摄影都有三原色的混合问题。随着彩电的普及,人们容易对什么是三原色产生疑虑,究竟是“红、黄、蓝”还是“红、绿、蓝”? 我们知道,外界的光学辐射作用于人的眼睛产生颜色感觉,物体的颜色既决定于外界的物理特性,又决定于人眼的视觉特性。人眼对380～780nm波长范围的光辐射作出选择性反应,从而看到各种颜色。人眼视网膜上能分辨颜色的锥体细胞有三种神经纤
Color TVs and color paints, printing and photography all have mixed primary colors. With the popularity of color TVs, people tend to have doubts about what is the three primary colors. What is “red, yellow, blue” or “red, green, and blue”? We know that external optical radiation acts on human eyes to produce color perception. The color is determined by both the physical characteristics of the outside world and the visual characteristics of the human eye. The human eye selectively responds to light radiation in the wavelength range of 380 to 780 nm to see various colors. There are three kinds of nerve fibers in the pyramidal cells that can distinguish colors on the retina of human eyes
