If something is rainbow, it is something really good and sweet and fun, and a bit silly.

Rainbows are possibly ninjas in disguise.
It is also said that they may be covered in giant invisible cloaks.
dancing in the rain is rainbow.
It is rainbow to sing aloud even if it sounds horrible.
It is rainbow to being awake at 3 PM and writing about rainbows.
