大侠不用回答了,我已经知道了

Biological basis
Primary colors are not a fundamental property of light but rather a
biological concept, based on the physiological response of the human eye to
light. Fundamentally, light is a continuous spectrum of wavelengths, meaning
that there are actually an infinite number of colors. However, the human
eye normally only contains three types of receptors called cones. These
respond to specific wavelengths of red, green, and blue li

貌似没有这么简单
事实上并非红绿蓝能构成基色,黄品红青(yellow,magenta,cyan)也可以
而且用红绿蓝并不能完全模拟人眼所看到的所有颜色,有一部分色域是缺失的
