I see a lot of restored labels where the only restoration is color touch. As a hypothetical, if the color touch was, let's say red, and you marked over it with a black sharpie, would the book then get a universal label without the restoration label? What if you took it further, and had an artist sign or remark completely over the color touch?
I'm not sure if CGC would consider this "gaming the system" or if it might be a violation of one of their policies, but was curious since a color touch restoration is seemingly done to improve a book's appearance by covering up a defect, and in these instances you are not attempting to restore the book's condition, but replacing it with a new defect.
