小学英语译林牛津版三年级上册颜色的起源宇宙起源时就只有一种颜色,原因是宇宙各部位的密度相等,没有运动存在,后来有了运动,也就产生了颜色的多元化!颜色的形成简单的说就是擦与混的过程：擦指的是通过擦的过程,给物体造成中空,也就是把物体无限薄化中空,看到的颜色与眼睛的精度有关.混指的就是把擦好的颜色与原来的颜色相混,使颜色密度不同,使眼睛产生误差(即眼睛相消与相叠不同密度的颜色,也可以无限循环这个过程),看到的颜色也与眼睛的精度有关, 就这样可以产生人类所说的三原色,也就产生无数种颜色.眼睛精度与眼睛接受的物体哪部分颜色信息有关,也就有了色盲这种病. 天是蓝色的，为什么不说天是红色的呢？答：首先你得明白一个道理：我们周围的事物之所以显现出颜色来，仅仅是因为阳光照射着它们。

虽然阳光看上去是白色的，但是所有的颜色：赤、橙、黄、绿、青、蓝、紫，在阳光里都存在。

天空里有这么多颜色，为什么我平时看到的只有蓝色呢？你可能会问。

如果你把光线设想为波浪，你就会猜破这个谜了。

光其实是像一个波浪那样在运动的。

我们来设想一下一滴雨落在一个水洼里的情景。

当这滴雨落到水面上时，就会产生小波浪，波浪一起一伏地变成更大的圈，向着四面八方扩展开去。

如果这些波浪碰上一块小石子或一个别的什么障碍物，它们就会反弹回来，改变了波浪的方向。

而阳光从天空照射下来，一样会连续不断地碰到某些障碍。

因为光所必须穿透的空气并不是空的，它由很多很多微小的微粒组成。

其中百分之九十九不是氮气便是氧气，其余则是别的气体微粒和微小的漂浮微粒，来源于汽车的废气、工厂的烟雾、森林火灾或者火山爆发出来的岩灰。

虽然氧气和氮气微粒只是一滴雨水的一百万分之一，但是它们也照样能阻挡阳光的去路。

光线从这些众多的小“绊脚石”上弹回，自然也就改变了自己的方向。

可是那么多颜色的光改变了方向，为什么只有蓝色被看到呢？你可能还是不明白。

我们还得回到刚才说的那个水洼里。
