Summary

A dark titlebar when dark mode is enabled.

Examples

Context

The white titlebar greats a visual disruption and also hurts the eye if dark mode is enabled in other places such as in Windows shell, browser etc.

Possible implementation

There is an API (undocumented) introduced in W10 v1809 that changes the titlebar color for Win32 apps:
