Painting Stairway Entrance Wall - Finally

Everyone has those projects that they hold off on doing and my stairway entrance wall is one of of those projects.  My condo is located on the "2nd floor" no one lives below me, my condo is above a bunch of garages.  In order to get into my condo you have to walk up two flights (but not full flights of stairs).  The first set of stairs has 9 or 10 steps and the 2nd half has the same amount.  In between the two sets of stairs is a landing and walls that lead up to the vaulted ceiling.  Here's a view of the wall that I'm looking to paint:

This is a view looking down from the top of the stairs down to the landing and the wall that I'm looking to paint (the big white wall).  The picture doesn't really show it but, this is a two story wall.  Let me see if I can dig up a better picture....

You can see the wall in this pic.  Yes there are 2 white walls, but the wall on the left that is half painted and the other half is white, is not something I can paint myself.  I don't have a ladder that can accommodate stairs nor one that can accommodate stairs and a 2 story wall at the same time.  I want to paint the wall on the right hand side. It's the wall that's behind the horrible ceiling light, this is also on my list of things to replace!!  So if anyone wants it, it's yours.  Anyways you can see that this is a very tall wall.  You can also see from the two above pics that khaki, tan or whatever you want to call it color, is the color of my stairway entrance and the same color up stairs in my living room.  I should look up the color and let you know the exact name.  What I can tell you is that it it's the Behr primer and paint in one Premium Plus Ultra line.  The best invention ever!!!  The other main color is blue, but in shades that range from light blue to medium blue with a few pops of cobalt blue.  What I'd like to do is paint that wall an accent color of one of the various blues that I have in my living room.  I think that will add a little bit more character to the my open space living area.

The problem was I couldn't decide which color I wanted to paint.  One thing I love is that most of the major paint companies is that you can order or buy samples of their paint in the major home improvement stores.  So I just purchased 10 - 8oz sample colors of various shades of blue of the Behr Premium Plus Ultra paint.  So as soon I receive the color samples I'll paint a bunch of different swatches on the wall and figure out what color is the best one to paint the entire wall, then I'm off to Home Depot to purchase a gallon of paint.  I've been thinking about possibly using the same color and paint the kitchen the same color.  I'll keep you posted as to the color and what I decided to do with the kitchen.  Too much khaki and tan in one place isn't doing it for me anymore.  Till my next post...
