Eli5 – Why does air “looks” colder in winter ?

227 views

So, temperatures are dropping below the 0°C where I live, and I was wondering why does it seems like everything has a “cold color” filter applied to it ?
It’s almost like I have a veil in my eyes that makes everything I look at outside whiter or greyer, even when this is bright sunny, and I really don’t think it is something about a psychological bias because I do prefer colder seasons over hotter ones.

Thanks in advance !

In addition to what’s said, the actual things we look at get muted in various ways: flowers die, trees fell their leaves, clorophyll is no longer regenerated, so vegetation gets a lot more muted. Frost covers objects and adds a white layer on top of their colors, making them look more grey and less vibrant. Dirt and grime is no longer washed away by rain, and accumulates wherever vehicles, humans or animals move a lot.
