ᐅ Which color should be chosen for the front door, window sills, and roller blinds?

Hello everyone,
We are now close to finalizing our town villa, and I have fallen in love with an unusual window color: metallic gray-beige combined with an anthracite-colored roof. Now we are facing the challenge of deciding the colors for the front door, shutters, and window sills. Our first thought was to keep everything else simple and choose anthracite to match the roof. But would that create too harsh a contrast with the windows? I have attached an example photo—it is not our house, just to illustrate the color of the roof and windows. Although the window color doesn’t come through well here. It is really a metallic brushed gray-beige. Many thanks in advance.

I think a front door can be colorful and stand out from the house. Ours is red, and the doors of the boys are blue and green respectively. Gaulhofer with a round window, the colors are strong and rather dark; I would have to look up the exact RAL. So far, everyone has liked it. OK, hardly any guest will say, "Wow, that looks awful" – but you can usually tell quite well when someone's words and body language are too incongruent.
