Legallity of requiring rental repaint upon exit?

I am vacating a commercial space after 2 1/2 yrs. There are some issues regarding the walls and the need to be repainted or repaired. We contacted landlord and requested sample paint- it was painted prior to us moving in. She wants to repaint in different color which would obviously increase the cost associated with it. Initially she wanted us to foot the bill we replied that we felt it to be unreasonable- she backed off and said she would split the cost. Because, there is little touch up required, we still feel that this is unacceptible. The lease states that we are responsible to repaint. Is this binding? Is the implied meaning of the provision to only return the property to its original state, thus not to paint the property in its entirety? Are we required to change the color? - Is this your question? Add additional information
