I've long been of the firm opinion that when it comes to color, your pillows should not be the same as your couch, favoring instead a pillow color that complements and contrasts against the shade of your sofa. Orange against a blue background for example, or a light shade of pink against a sage green.
But others would contest that the mix-and-match look can easily become outdated, and for a more elegant, sophisticated look, matching your pillow color to your couch is the way to go.
