Blue and grey are the colours we usually expect to see in the sky, but as July rolled around San Francisco experienced something a little different.
The sky instead appeared to have something of a sepia tone, prompting those in attendance to take photos of the city looking as if someone had put an Instagram filter over the top of it.

San Francisco sky is bizarre right now. Rayleigh scattering through this cloud is depleting all the blues and leaving us with a sepia sky. pic.twitter.com/weUDCkulsN

The images were indeed without filter, giving them a nostalgic vibe usually reserved for album cover artwork.
San Francisco looks like someone forgot to turn off global instagram filters.

Reports say that smoke and ash from wildfires in counties north of the city were the reason for the phenomenon, colouring the sky and showering some areas with ash.

So while the sky may look pretty, it could actually be dangerous.
That didn’t seem to be a concern of music artist Dua Lipa however.
