Help! ...I need to lighten up my life :)

So I posted my living room on HGTV rate my space and the girls all agree it's a little dark in here.  I was thinking about adding a light couch...like this one from ikea.  I saw it on My Sweet Savannah blog.  Do you think this would go well in my living room (picture feature below)---I am trying to light it up a little!
