If i were flipping it i would look to give color.  

Others to also look at is providing custom paint colors for 1 or 2 rooms. 

This 3BR house has only been vacant ten days and a lady looked at it and said she will sign the lease if A-- we paint the kitchen a different color, and B-- if we let her put up a chain link fence around the back yard at her own expense.How does this sound to you guys?

He said the colors don't match with his decors.

I would look at adding some annual flowers with color.  

And make sure that right is grandfathered in.Oh, and the same board, while I was on it, chose new paint colors for the complex.  

It doesn't necessarily refer to color, you can use it with any color, or white for that matter. 

I would offer a color pallet for the tenant to choose from. 

Something that helps me is I have a provision in my lease that describes the paint brand, texture, and color of every room for future reference.

Even if you have to offer a small tenant concession, it's worth it.Speaking of concessions - I offer something small [like a ceiling fan or one room of custom color paint] for them to sign another term once the current lease is about to expire.Also, I assume/hope you have a rock solid lease.
