Palette

We understand your concern regarding the color palette appearing dull on your Galaxy S25 Ultra after updating to One UI 8.5.

Please check the following display settings, as they can affect how colors appear on the screen:

1. Go to Settings > Display > Screen mode and select Vivid.
2. If available, tap Advanced settings and adjust the color settings according to your preference.
3. Go to Settings > Display and temporarily turn off Adaptive color tone.
4. Check Settings > Display > Eye comfort shield and turn it off to compare the display colors.
5. Go to Settings > Accessibility > Vision enhancements and make sure Colour correction and Colour filter are turned off.
6. Samsung notes that these features can affect screen colors and brightness, while the Vivid screen mode allows you to enhance the display's color range and saturation.

If the colors remain unusually dull after checking these settings, please let us know whether the issue affects the entire display or only the Color Palette/interface, so we can provide further guidance.
