I give up.
After a couple of weeks of stuggling to pick a color for my house, I realize that the colors in my head do not exist in the real world, so I give up.
I'm getting the house painted with two different shades of gray.
Woo-hoo.
The garage doors will be painted white.
Double woo-hoo.
I figure I'll get the house painted gray, regret my choice for a year or so, then learn to live with it.
