Gray/Anthracite-colored windows - the new "white"?

Here: it was about RAL colors

According to my forecast, red roofs again from 2025

The trend might not materialize. The trend towards heat pumps also "fuels" the trend towards photovoltaic systems, and these simply suit dark roofs better than red ones. History repeats itself, but there are also game changers.

The anthracite in RAL 7016 shimmers blue in the light, we do not like that. We have decided on quartz gray RAL 7039. Inside white.

In the end, it’s a matter of taste. It would have bothered us.

If you consciously choose anthracite - whether inside or outside - then you like it. Let’s assume that. And then it’s totally fine if you can see it whether the door is open or closed.
But to each their own - not everyone has to like anthracite.

outside aluminum, inside white-painted wood. By now, I would definitely go for all-metal windows. But 10 years ago, I couldn't come to terms with the idea, it seemed too 'industrial' to me.

Sure, it could fail to materialize. Photovoltaics really do look better on dark roofs, but only the modules without thick aluminum frames. Otherwise, it looks just as bad. But is that really a decisive argument against the red roof? For me, not at all, I also have a red roof and at some point there will be photovoltaics on it.
