Other creatures are also iridescent, creating the rainbow effect when colors change when looked at from different sides.

其他生物也有五彩斑斓的，从不同的角度看时，颜色会发生变化，产生彩虹效果。

Bolder Baking and that was for marbled Rainbow Cake. But today we're going jazz up this already amazing cake and create a double rainbow effect.

Bolder Baking 是针对大理石彩虹蛋糕的。但今天我们要让这个已经很棒的蛋糕变得更加活跃，并创造出双彩虹效果。

So to truly make this a Double Rainbow Cake, we're going to color our frosting just like we did our cake to create a beautiful rainbow effect around the outside.

因此，为了真正制作出双彩虹蛋糕，我们要像给蛋糕上色一样给糖霜上色，以在外面营造出美丽的彩虹效果。
