Windows 10 Border Color Remove?

[Zephis]

Hi so this thing has been annoying me and I swear it wasn't always there but I'm not sure. Here is a photo to show you what I'm talking about.

So is there anyway to remove that red line that appears around the window?

seems that happens with any theme colours you choose or let windows choose, I did not notice it until I selected the red colour like you have, I use blue barely see it.

AFAIK there's no way to accomplish this at the current update level.
One suggestion might be to use dark mode and change it to a light grey instead.

The functionality you are asking for is not exposed in Windows 10. Your options are to pick another color, as The Paladin suggested, or lump it.

Microsoft may give you back that feature in a future update. My suggestion is to look through the user feedback and up-vote any regarding your concern. If you can't find the topic to up-vote, create your own. Make sure the devs know it's a concern.
