AFAIK there was a time in W10 you could create your own design but that was killed by one of the spring or autumn updates.
Here it is, with comments customized to the international version.
Please do not hesitate to give me hints if you discover errors in it.
; Reminder: Used Colors in skin.ini
; Background "dark grey" (near black)
; RGB 24,24,24 = #181818

; Please do not forget background color for each GUI screen object in mAirList Config.
