Came across this Win 10 color changer from
http://rammichael.com/tag/windows-10-color-controlBy checking/applying, turns background autocolor to something like wacky 8.
More bright colors. Still has dark colors. Just a different mixed set it uses.
Some colors could be too bright, if using original 10 menu.
Works fine in Classic Shell Menu.
The windows border works too, just only 1 pixel wide.
Heard that in a future Win10 upgrade, MS will put back selected top border window color,
so it would be more noticable at that time.
