I have several color segmentation methods in my File Exchange: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862 They segment the image into "foreground" (the objects of the color you want), and "background" (the colors you don't want). You can use the invert the foreground mask to give an image of just the background:
backgroundMask = ~foregroundMask;
% Mask the image using bsxfun() function
backgroundOnlyImage = bsxfun(@times, rgbImage, cast(backgroundMask, class(rgbImage)));

If you have the background portion of the image, then just binarize it, and take logical product with the original image.
outImg = origImg.*(backImg>0.5);
Here make sure that your dimensions are in order.
