Landlord, tenant butt heads over repainting costs

Question: I just moved out of an apartment that I rented for about 6 1/2 years. I had painted the apartment a terracotta color after asking the onsite manager for permission in advance. We never discussed the actual color that I would be painting, but he indicated that it was OK because the apartment would have to be painted when I moved anyway. I think the apartment looks much better in this color than the dull boring colors used by the landlord. Now I have moved out and I received my security deposit disposition statement with a deduction for $350 for repainting because I had painted the unit "dark orange." They claim the total cost to repaint was $950, as two coats were required. I feel that being charged more than one-third of the cost of painting to be exorbitant. If he had told me that the cost would be so high I would have painted over the color myself. Is there any advice that you can give me or should I just pay the additional amount and learn a lesson?
