“电影院座椅为什么普遍是红色的”引热议，网友：从没在意过，又涨知识了！

In a full-light situation, the red flower of the geranium pops out from the green background. But when the light dims, the flower quickly fades from a vibrant red to a much duller, darker shade. 

在光线充足的情况下，天竺葵的红花从绿色背景中脱颖而出。但是当光线变暗时，花朵迅速从鲜艳的红色变为更暗淡、更深的色调。

The greenery behind it, while also losing its vibrance, does so less quickly, arguably becoming more noticeable than the previously-dominant red flower. As even more light leaves, the entire scene becomes black and white.

其背后的绿色植物虽然也失去了鲜艳的色彩，但褪色的速度较慢，可以说变得比之前占主导地位的红花更加显眼。当光线进一步减弱时，整个场景变成了黑白色。

But you'll rarely if ever, see green or blue seats in theaters; those colors simply take too long to fade away, and would distract from the viewing experience.

但你很少会在影院看到绿色或蓝色座椅；这些颜色消退的时间太长，会分散观影体验。
