Neither. The light one would be too boring for me (which color is the facade?) I don't like the dark one in terms of color tone and surface texture. You asked...
We will have the window color Winchester. The window sills (metal) will then be painted in that color. One should not compare only windows with window sills, but the whole house. We have white plaster, anthracite-colored roof tiles, and windows in the color Winchester. We did not want to have a 4th color.
