My last house the front door was dark brown. The brown matched the garage doors and the corbels under the roofline.
Most of my houses have had white front doors. But, I did have one reddish brick house with a black door, and another house that was a brownish slurry over brick that had a medium brown stained wooden door.
For your house I think black or maybe a faux wood if you’re creative with paint. I didn’t see the photo though. Was there a link I missed? The style of house would matter for me regarding the door color. Black might be too extreme with a white house. It depends on the house. I like dark green also.
You could go to houzz.com and search “white facade” probably and see a bunch of ideas.
