I need your opinions again.

Okay, so in my backyard, I have this wall that goes across the whole yard.  This is not a good picture to give the full effect, but just imagine that there are flower beds all in front of it, and there are bushes and trees planted up on the upper level.  

I have already been busy the last few days out in the yard, and I really want to get this wall painted this spring, but I'll need to do it SOON, before everything starts growing, and most importantly, before all the little spiders start crawling all over it (because then I'll be too chicken to do it!)

So it was painted a brick color.  My question, should I be boring and keep it the brick color, or something similar, or change it to a more neutral, like a tan color, or go green?  or red? 

I do not want anything too crazy, because during the winter months I don't think I'd really like to be staring out at a bright yellow or blue wall, you know?  

What would you do?  I'm kind of leaning towards a dark green shade.

And for the planters:  if they don't sell by this Sunday, I'm keeping them, and more than likey will be spraypainting them colorful: yellow, red, orange, green, blue.
