If you’ve been scouting for a theme that can give your Windows 10 a unique, dark look while making the readability less strenuous,
then Grey Eve theme could be a great option to consider. Comprising a color palette of greys and blacks only, the visual style is as darker as it gets. Text remains in its glorious white so shifting from one window or file to the other on is easier, even at night.
Please take note that this theme doesn’t make any interface or design changes. All it does is ride on the flat Windows 10 design and more like sucks in all the lights off on the interface.
