It looks like Vanessa has posted three color options for this wall on her Flickr page. Vanessa shows a bright blue, green and red - all without the commitment of painting and re-painting. I vote for the red!
While a little test paint will be the truest measure of a new color in a space, this test is easy and pain-free for anyone with the Adobe Photoshop program. What a great idea!! Thanks, Vanessa!
