I'd match the floor color (more or less). I looked at the colors and "soft wool" might be the right color but I cannot tell from here.

Here is the professional way to match colors: http://www.lindaholtinteriors.com/2011/07/testing-wall-color-101/

you could use a lighter shade of a similar color, or leave it alone and paint the dark woodwork. getting rid of W2W carpet to make the space breathe better.
