ᐅ Naming a Part of the Roof

Hello roof experts,
is there a specific name for this silver-gray rail/strip/gutter/thing that can be seen in the photo here between the roof tiles of the main roof and the bay roof?
And related to that: Is it normal for it to be this wide and prominent, or could it be made less noticeable somehow (for example, painted black)?

This is the so-called valley; the flashing (if it is flashing) corresponds to valley flashing. Trade: roofer. In my opinion, the tiles are cut very generously here.

This is the roof valley, or rather the flashing. The width is necessary to direct the water away. It usually looks like this, and if you don’t like it, remember: you get used to it 😉

Perfect, thank you for the quick response!

Furthermore, the red color you see is definitely not rust but the dust from the cut roof tiles, which will wash away and look better.

Yes, that is also our assumption and hope. When comparing with other houses, we noticed it looks quite wide, but well, maybe it rains more over our house... ;-)
