When we moved into our house, we really didn't like the green in the bedroom or the office (which will eventually become the nursery). The guest bedroom also needed a new look. So, as we started thinking about new color schemes, we quickly realized we weren't redecorating the office, we should be thinking of it as decorating the nursery.
We initially chose a mint green and a yellow from the Benjamin Moore Pottery Barn Fall 2010 collection of colors. We're not sure either color is doing it for us on our test wall, so I think we're headed back to the drawing board.
This prompted us to think about what colors babies like. There's a lot of opinion all over the web, with a lot of people saying that the biggest thing to do is pick a color scheme that is calming and relaxing to us. We will do that, but some research suggests that babies prefer certain hues, too -- mostly blues and purples.
In this research, the size of the white dot indicates the length of time the 3-month-old babies in the experiment looked at a given color. Looks like the greens and yellows we picked initially are just about the worst choice!
Our friends in LA are having a baby girl but still chose a light blue for their nursery. We might do the same, possibly with a darker blue as an accent wall. (And, of course, some wall decals and art to spice things up.)
