Cortana search bar color

Brink, our admin, has a wonderful tutorial on this subject :

May I be so bold as to post an alternative which will change the search bar from White to default Grey.
*** if this method has been posted here before, I apologize. ***

Settings > Time &n Language > Region & language > change Country or region to a country not accepted by Cortana, such as Gabon > reboot.
Cortana search bar is changed to grey colour.
After reboot, back to Region & Country > change the country back to the original one.
Cortana search bar will remain grey in colour.

Hello David, :)

You might see if the method in the tutorial below may be able to change the Search box back to white for you.

No, it does not go back to White using your tutorial above. So what should be done ?

Wait. It DOES go back to White.
