If your interior is mostly bright/white colors, if go with black to give a contrast. And vice versa.

IMO if you have grids and a more traditional interior go white if like the modern style forget the grids and go black.

Thank you!! Here are some photos. Trim is creamy white and walls are “basket beige”. Curtains will go away.

i have no idea, are these paintable down the road? if not, go with white. black is trendy now but a detriment in the future if they can't go white.

i like black... my wooden sashes are black on the outside. havent had any desire to paint the inside black tho.

I'm with ninigret on this. I believe that white will work better for your house due to the style and colors you have in your rooms. The only place I have gone bold enough to paint interior doors black are in my entryway. It's painted a cool, medium gray with bright white semi-gloss trim around the window, door frames, and woodwork. I also have black photo frames in my entryway and the black doors play well with all of it. I will not be introducing black doors or trim anywhere else in my house.

Thank you Ningret and Bev. Since we are going with vinyl I presume they are not paintable. So white sounds right?

What about grid - which sounds better?

Yes! We have white vinyl windows and what I love about them--I do not have to paint them! We have windows with grids, which are very normal for the area I live in.

I hate muntins (grids) on windows. A lot also depends on what the exterior looks like. Does the house need grids or is more of a modern style?

Here are a few images of what the floor length windows can look like (I would do none) . is white /black the only choice? what about tan or gray windows? what if you did wood interior, vinyl exterior? that way you can paint the inside. for the floor length windows, or the really nice view windows, I might spend a bit more and get better quality.

personally I like these following two windows and styles....
