Black for sure the white is too in your face and looks cheap IMO

May we see the black without the string lights in order to compare better? Or add them to the white please.

I like the white windows better, because your house is very dark. It might just be the picture you took. I don't like the white around the door. You need some greenery in front. All that cement is grim. Just two pots of flowers would go a long way.

Black

The strings lights have to no matter what. The white at the bottom of the door too. Also i agree some big pots filled with color and seasonal stuff goes a long way to brighten any home

do you need a bay window? a flush window the same size would be an upgrade.

why just black or white, there are other options. The dark siding makes the house look especially short.

Black, Black, Black!

Dark coloured window frames tend to be more popular on modern house designs as the darker frame creates an optical illusion, making the frame appear slimmer. White frames often appear as 'chunkier' despite being the same size. However, true black frames can sometimes look 'dull' offering no texture, depth or reflection in daylight. Architects and designers will often opt for a dark grey to get the slim design to the window frames whilst providing some texture and depth. That is why 'antracite grey' (RAL 7016) is one of the most popular window frame finishes on all our projects across the world!
