Are you able to upload a pic showing that red hue?
And does the Picture Test show it? Settings > Support > Self Diagnosis > Start Picture Test.
Say "Hello!" to the Community in The Introduce Yourself Thread.
Could you send us an image of the Picture Test?
If it appears during the Picture Test then this would be a Hardware Fault and it is best if it's inspected by an Engineer.
