缤纷的色彩总是环绕在我们周围。它们映入我们的眼帘,无意识地吸引着我们,但是从主观角度却很难解释清楚。如果给一个色盲患者描述绿色是什么样子,其难度是很大的。尽管很难描述清楚颜色,但是科学家和艺术家们也慢慢地掌握了很多关于颜色的知识。最基本的就是:所有的颜色位于光线之中,而不是位于客观物体之中。当光线落到物体上,它的表面就吸收了一部分光线,剩下的光线就反射出来,人眼可以看到。肉眼所得到的光线信息又通过视觉神经传到大脑,在这里将颜色印象进行加工。颜色印象又会因人而异,因为根据位于视网膜上接收器的数量和功能的不同,所看到的颜色质量也会不同。
Colorful colors always surround us. They come to our attention and unconsciously attract us, but they are difficult to explain in a subjective way. If you give a color-blind person a description of what a green color looks like, the difficulty is great. Although it is difficult to describe the color clearly, scientists and artists have slowly mastered a lot about color. The most basic is that all the color is in the light, not in the objective object. When the light falls on the object, its surface absorbs a portion of the light and the rest of the light is reflected and visible to the human eye. The naked eye light information is transmitted to the brain through the visual nerve, where the color impression processing. The color impression can vary from person to person, because depending on the number and function of the receptors on the retina, the quality of the color you see is different.
