Check if greyscale mode is turned off in accessibility settings.

Try resetting picture settings.

Check your cables, or components that may be outdated or worn.

Or power cycle the TV.

Hey, Parrori, thank you for sharing this concern with us. You may need to reset the picture settings. To make sure there isn't a problem with the TV itself. Try performing a picture test on the TV.  
On 2022 and later TV models: Navigate to All Settings, then select Support, then select Device Care, and then select Self Diagnosis. Select Picture Test, select OK, and then view the test. You can select Yes if the picture looks normal, No if there is a problem with the picture.
If there is a issue with the settings of the picture. Reset the picture by going to Settings > All Settings > Picture > Expert Settings > Reset Picture.
