Well, maybe because that teal shade is casting everything within its glow.

What I do is go ahead and paint a big portion of the wall with a stark white, like a pure white primer, or something really white. Then I paint a posterboard in each color I'm considering. Then you can carry the posterboard around, look at it next to the wood and other colors in your home, etc. Look at it on each wall, near windows and in darker places, like corners. Hold it behind the furniture.

I know there's some kind of service (is it called "Samplize"?) where people order many brands of paint colors on something like posterboard and it's delivered to you, without having to purchase all the paint (and then dispose of it all). It's probably a good idea.

Yes, the teal is throwing me...
