Video Description

如果我问你,大海是什么颜色? 蓝色!蔚蓝色!你可能会不假思索地回答。 因为天空是蓝色的,所以海水反映的颜色主要是蓝色。但在某些特定的环境下,海水是绿色的,像碧绿的翡翠。在金色阳光的照射下,海水又会呈现出金色,像是铺了一层金帛。有时候,天空挂满紫色的晚霞,此时“落霞与孤鹜齐飞,海水共长天一色”,海水又变成了紫色。而在阴雨天里,大海会收起所有的彩色,变成一片青灰。事实上,以上我们看到的这些颜色的变化,都只是表面现象,在200米以下的深处,大海其实是黑色的,因为没有阳光投射进来,这里漆黑一片。我们现在可以形成一个完整的影像:大海的主体其实是黑色的,表面浮出蓝色、绿色、紫色、金色、灰色等等变化无穷的各种颜色。 以上关于大海颜色的描述,恰恰可以用来描述我们这期视频的主角——大溪地黑珍珠:主体是黑色,表面可能泛蓝色、绿色、紫色、金色、灰色等等,变化无穷,丰富多彩。 本期视频,我们就来全面了解这种大海里长出来的黑金,最神秘优雅的精灵。
