Leather Car Seat Repair?

There is a small part of my leather seat of my car that is damaged.I was using a "so called" leather safe brush and it looks like the dye on the leather came off. Its not big but it bugs the heck out off me. Its about 3 inches long and1 inch wide. I had the curiosity of what would the price be to get it repaired if i was to take it to an upholstery shop ? Or buy a dye or some sort or paint to cover it. Thanks in advance.
