A double rainbow graced the sky over Washington, D.C., to cap the start of the week.
On what was otherwise a cloudy, rainy day, photos of the colorful weather phenomenon were shared by Twitter users Monday evening.
If you are in DC go outside and look up. There is the clearest rainbow I have ever seen. #Rainbow #DC #Weather pic.twitter.com/wb7tFsBXgR

While some observers only saw one rainbow, others were lucky enough to catch a glimpse of a double rainbow.
The pictures never look quite as gorgeous as the real thing, but I guess this double rainbow view from my balcony is a good reward after getting caught in a DC downpour. pic.twitter.com/ngqDvwZ1aV

D.C. is no stranger to double rainbows. One appeared above the White House last August, documented by awestruck journalists in the vicinity.
A rainbow is a multicolored optical illusion, which appears in the form of an arc, which is created when light hits water droplets. According to National Geographic, a double rainbow occurs when light is reflected twice in raindrops, resulting in a second arc with its color scheme reversed.
