Anthracite windows - Which roof color

For a gray facade, I don't like anthracite windows. But I don't really like them anyway. You see, it's simply a matter of taste [emoji6]

Yes, that's true,
But you always want opinions,

.... I would go a bit lighter with anthracite windows.

Anthracite is not anthracite. And "lighter" is not a color term either. You should get the RAL code, after all, there is also a shade of gray that leans toward brown, and that could look very good with the roof tile.

No idea, the offer only states Anthracite. Do you somehow have a picture of the shade you have in mind?
