Combine venetian blinds and roller shutters at the house

We also plan to mix venetian blinds on the ground floor with roller shutters on the upper floor. How did you solve the issue with the colors of the slats? The same color for both? And if so, which color did you choose?

We have both in aluminum color. But it doesn't really matter, since the venetian blinds get covered with pollen every year, so you never really see the color anyway ;-)
We specifically decided against anthracite color because the pollen is even more visible on that than on aluminum colored ones.

We saw our venetian blinds live for the first time yesterday and I am super happy that we chose RAL 9007 for the aluminum front covers of the windows, rails, window sills, and venetian blinds/roller blinds. There is a slight color deviation between the venetian blinds and windows, but that is also due to the different surface structures. Unfortunately, I don’t have any photos yet, it was just a quick test during installation..
