To turn on Google day mode in Google Maps, open the app, tap your profile picture, go to Settings , then Navigation , and set Color scheme / Map display to Day instead of Automatic or Night.

In Google Maps

  1. Open Google Maps.
  2. Tap your profile icon.
  3. Go to Settings.
  4. Open Navigation.
  5. Find Color scheme or Map display.
  6. Select Day.

That keeps Maps in bright colors while navigating, rather than switching with the time of day.

In Google Search

If you meant the Google homepage/search page, open Google, tap Settings or the gear icon, then choose Dark theme off or switch to Light / Appearance depending on what your device shows.

On Chrome

If you meant the browser, open Chrome > Settings > Theme, then choose Light or turn off dark mode.

Quick note

“Day mode” can mean different things across Google apps, so the exact steps depend on whether you mean Maps , Search , or Chrome.
