A closer look at the new light theme in coming to Windows 10

Last week, Microsoft started testing a brand new light theme with Insiders that's expected to ship in April 2019 with the 19H1 release. Although it's not finished, this early implementation of the light theme is a great start and an excellent addition for those who love options.

The new light theme in Windows 10 19H1 turns not only themes your apps, but the Windows Shell too. This includes the taskbar, Start Menu, Action Center, notifications, touch keyboard, and context menus (in some places) which gives the light theme a much more consistent feel.

Like dark mode however, it isn't entirely consistent. There are still some areas of the OS that are themed dark, such as Cortana and My People. Since it's still early days however, we should expect to see Microsoft theme those areas as well to match the rest of the OS design when light mode is enabled.

Many icons on the taskbar will switch their icons from white to black if the developer has provided the assets for it, which makes your open apps easier to see on the lighter taskbar. If a developer hasn't provided the assets for light theme, Windows will automatically put those icons into a colored box to ensure you can see them.

This only appears to happen with apps from the Microsoft Store, however, and now with Win32 programs downloaded from the web. This means that if you use an app with a white icon from the internet, you will have a hard time seeing that app open in the taskbar unless the developer provides a light theme version of their icon.

The other issue with the light theme right now is that Fluent Design reveal and translucency effects are a little harder to see within the Windows Shell right now. I assume this is just down to tweaking things a bit, but I'd love for the reveal effect to be darker when light theme is enabled so that you can see it like you can when dark mode is enabled.

Overall, this first version of light theme for Windows 10 is great. It's clean, fresh take on the Windows 10 UI that I'm sure many people are going to enjoy. There are a few teething issues right now, but nothing out of the ordinary for a pre-release feature that's still months away from being finalized. We can't wait to see how this improves.

    I think this may have been the main reason it took them this long to do this.
  • This is so annoying everytime Microsoft releases a nice new feature, it always comes in another feature update for next year. I think there should be one big update every year and then Microsoft can have time to properly iron out the bugs before realeasing a feature update.
  • As it has been explained before, this wouldn't actually make any difference to the quality of updates. It isn't the cadence that negatively affects quality but rather the process itself. Microsoft could ideally release an update every time a new feature is ready and be much more polished and streamlined than it is now. Or they could release an update every three years and have it be just as buggy.
  • Thank you! I've been saying this since the first Windows 10 release.
  • This idea wouldn't fix that you see new (nice) features that aren't implemented yet. You'll still see the upcoming features, because the Insider Program exists.
  • This is much better than the dark theme. The dark theme is too depressing.
  • My soul is black, so... 😂
  • Instead of this light or dark option, I'd prefer to have a more consistent window colour selection experience like was present in Windows 9x, 2000 and to a degree, XP. That way, I'd be able to set a tan coloured theme which would run across all applications.
