refractive indices of colours

If 7 colors of white light have different refractive indices in a medium then they should have different refractive indices in air as well. Then why don't we see splitting of colors in air.

Dont wee!!!

What happens in the evening when it gets reddish!

and yeah in the noon time there is none.. bcos the rays are perpenicular!

So no diffraction..

If you pass white light through air or vacuum, shouldn't it split?

it does split in the air..

only that there are no rays.. it is a beam of light.. so most of the time, we wont realise..

it will just mix back..

except in evenings when it appears red..
or for that matter why does the sky apprear blue?

Isn't it more related to scattering due to dust particles ? So what about vacuum ?
