I mean there are a few details involved here.
Is this a phone you're talking about?
A PC?
A Mac?
Something else?
That's why a screenshot helps, because as the saying goes, a picture says a thousand words.
As far as things looking discolorized that could be because accidentally we may select or touch a part of the screen.
Here's how that error would look under my PC for example:
View attachment 257984
And how it should look normally:
View attachment 257985
Again, i don't know how it looks on your end, but a screenshot would help.
