iridescence

Tiny layers in the wing scales of blue morpho butterflies reflect light at multiple angles, leading to the interference patterns we see as iridescence..蓝色大闪蝶翅膀上的细微层状结构会以不同角度反射光线，从而呈现出彩虹一般的干涉图样来。

The huge pool of blood in front of her was already assuming the iridescence of coagulation; and when the sun rose a hundred prismatic hues were reflected from it..她面前的一摊血水已经凝固了，宛如彩虹的色彩；当太阳升起来时，上面就反射出一百种光谱的颜色。
