Deleted reward livery

I have deleted livery that I have received from Turn 10 on my 2014 Chevrolet #3 Corvette Racing Crovette C7.R. Is there any chance to get this livery back? My car is yellow now however it used to be silver. Any clue?

Depends on the “type” of gift livery (custom to the car or not). Go paint the car and choose manafactury paint. If that does not restore it, it’s unfortunately gone forever. Only T10 can then help.
