iridescence

You can see the iridescence on their faces.

你可以看到他们脸上的彩虹色。

When sunlight or moonlight passes through a layer of thin clouds, the result can be iridescence.

阳光或月光穿过薄薄的云层就会形成虹彩。

For day by day he felt more and more like a bubble filled with darkness, round which whirled the iridescence of his consciousness .

他日益感到自己象一个充满黑色的泡沫，四周缠绕着自身意识的彩虹。
