In my opinion, there are no special problems if the windows are white. But when decorating rooms, it is worth using combinations of gray and white somewhere, for example in textiles or decorative items. Show the whole room, please.

It would be the whole house. This was just to show the two together. it was the asiest way to show the two colors together. The sun was also a problem trying to get pictures. That is good to know to have gray and white in the room somehow. That is an easy thing to do.

I understand that it won't be limited to one room) Just using one room as an example, you could probably sketch out different ideas here. If you want, of course.

I prefer my windows the same color as the trim. I would paint the windows too.
