I have fixed this problem. HDR should take the blame for this problem. When turn off HDR, the colors are normal.

Remmina using RDP can connect to an HDR desktop just fine, so I'd say it's a shortcoming of the protocol that RustDesk uses. Not sure if this issue should be closed just because there's a workaround.
