Help me pick a color!

Nick has been on vacation with his bosses for their annual trip to watch some college football, so I had the house to myself.  I usually plan a project during these times, and this time, I decided to paint the small guest room/cat room.  

The original color was Eggnog by Behr.  It was the color that was on every wall in the house when we  bought it.  It bright daylight, it looks like eggnog, but when its cloudy outside, after  dusk or under incandescent lighting it looks more butter/yellow in color.  I don't like the color very much.  I'm slowly going to paint every wall in this house to get rid of this eggnog color.

So here's the eggnog room:

 

So Thursday night, I started to edge out the room with Gentle Rain by Behr, but by the end of the night I was starting to think it looked a little too purple.  I waited until the morning to see it in daylight.  Daylight did not help, it looked like gray and pale lavender mixed together.  That was not the look I was going for.  My options were limited:

1. Live with the purple

2. Buy a new color

3. Mix my own color with left over paint from the bedroom (Harvest Brown by Behr).  

 Since I was looking for brown-gray color, I mixed my own color.  I had about a 1/2 quart of the Harvest Brown, and added that to the gallon of Gentle Rain.  In the can, and as I rolled it on, it looked like a boring beige, but when it dried it looked more gray. 

Here's the hand mixed color:

 

 Depending on the lighting, it's a gray-brown, or a gray-faintest hint of purple color.  This room will going through a large transformation in the next couple of months.  I will keep you posted with all the updates.  

I also finally got a mat for a print Nick's parents gave him about 2 months ago.  As with most of the prints we get, the frame is from Ikea, and the mat is custom ordered from Michael's.  It's a cheap way to get a custom look without the price.  This one was about $30 for the frame and mat, much cheaper than the $100+ we would have paid to get it custom done. 

 Since the paint color debacle in the guest room, I decided to get more paint chips to choose from for Nick's office.  I was planning on painting this room Gentle Rain like the guest room, but since that is too purple, I'm back to the drawing board.  So I need your help, which color do you the most?

So which color do you like the most?  (4 is not the wall color; it's Baked Brie, not Eggnog) I'm looking for a brown/gray color.  These vary from more brown to more gray. 

PS. It's the Week 1 in the NFL! Go Packers!
