Tenant Damaged Walls

[Loy G.]

Did a pre-move visit on property and tenant pointed out several spots they know they damaged walls in several locations throughout the house.  They said they were going to patch and paint them.  They are now contacting me saying they cannot properly match the wall colors ( I have offered the original paint chips) and they want to know what I want them to do.  I need a way to word my response that they don't use it as a means to be off the hook for the painting work that will need to be done after their move out.  

Suggestions?
