I quit talking to my mother a year ago. How do we repair the damage?

In June 2010 I was so excited about my mother moving in with me, that I fixed up two rooms and a bathroom for her in my house.
I was excited to make it beautiful for her, so I chose nice paint colors that would look good with the rugs she already owned and wanted. She had also requested the color teal in the room.
I ordered a large vinyl tree for one of the walls with beautiful teal and light teal leaves as a surprise for her. The expenses were a bit beyond my budget, but I knew it would be a beautiful place for my mother. Before the vinyl tree came for me to put on the wall, my mother came to see the room.
She noticed the one wall was "wedgwood blue" and commented on it. Little did she know that the wall would soon bear a gorgeous tree for her.

I remember she took my sister and me to lunch that day and then I went home to continue working on the rooms for her. There wasn't a lot said at the meal, but later that night I noticed her Facebook status said, "Teal is a shade of blue, but blue is not a shade of teal."

I was so pissed off because of her writing it on Facebook, and because she had NO idea how much work and money I had put into this incredible GIFT for HER!
I WAS PISSED and HURT!

So I wrote back to her on Facebook and told her she could kiss my blue butt and stay in her house with my 34 year old sister and paint every wall teal.

Then I waited for an apology.
And I waited.
And waited.
Well, she never gave it.

I am still upset.

I ended up putting up the tree about two weeks after the incident.
I sobbed and sobbed that my gift had been rejected and she did not appreciate my work, my gift to her.

I am still waiting, and I have not talked much to her since then.
I met with her about a month after it happened and tried to let her know how she hurt me.
I guess she didn't get the message, because there was no apology of any kind from her.

A week ago my brother came to visit, and we all spent some time together.
She said she needed help with her house. I said she had help. She asked who? I told her me, but she needs to make some amends. She said she thought she did, and I said no, she didn't.

I really want her to know that I worked hard on this gift for her and her rejection of it killed me.
I do not want to repaint the walls. This is not an option.

What should I do to get the message to her?
