Comic book colour touching is a form of restoration where you would, as an amateur (as a kid, most of the time), take a felt marker or a pen and colour-in parts of the comic book. As a professional standpoint it could be that the comic book has faded over time and the professional restoration expert will use colour touching to restore it back to its original form. Colour touch is usually viewed upon as a minimalist form in the slight range, but it will impact the value of a comic book.
