Others have also said it could have been cloud iridescence, which happens when water droplets or crystals scatter light.
其他的说法是，这可能是云彩虹色，发生在水滴或水晶散射光芒的时候。
Iridescence is proof that not every cloud has a silver lining - "some have tutti-frutti-colored ones."
虹彩的存在证明了不是所有的云朵都有银色的衬边——“有些云彩的衬边是五颜六色的。”
Iridescence can happen to any type of cloud, but is most common in stratospheric clouds in polar regions.
彩虹色色泽可以出现在任何一种云，但还是最常出现在极地的平流层云。
