The File Explorer icon also got a makeover since it was too light for the light theme. Text on the taskbar switches from white text on black to black text on white, and to avoid being lost on the task bar, some of the white icons such as mail and Store are color reversed to make sure they are still easily found. It also includes a new background, based on the original blue Windows 10 background, but lightened up to match the new theme. The color choices are clean and refreshing, and it really look great. The new light theme is a true light theme, affecting not only the app backgrounds but also the taskbar and start menu. In previous versions the default task bar and start menu color was black, but you could choose between light and dark for applications and most recently, File Explorer, which gained a dark mode in the October 2018 update.
But with version 1903, the light theme gets a major overhaul.
Windows 10 has offered both a light and dark theme for some time now.
