Carpet suggestions to go with grey walls

[fiorentina]

We've recently painted our bedroom Farrow and Ball Pavilion Grey and are having new curtains made in a neutral and grey pattern. The one area I'm struggling with is the flooring. Floor boards aren't good enough to sand and paint but we are struggling with finding the right colour carpet that keeps it looking smart and grown up as opposed to the rest of the house! Any suggestions really welcome. Thank you.

Dark grey? Or grey/blue stripe?

I have pale grey walls.Living room has ivory carpet,dining room oak laminate,my bedroom ivory carpet and ds room has a gorgeous grey,white and black stripe carpet.

What colour is your furniture?

Ps I know it sounds odd with 4 grey rooms and not the others but the others are a greyed white and greige (bathroom and kitchen wouldn't match the same grey
