Living Room Accessory Color Advice?

We just recently purchase a new living room set which looked beige/taupe in the showroom and once it arrived at the house it looks very gray :( All the tones in my house are very warm and the coolness of the couch looks odd. Hubby won't let me paint the current light beige walls with yellow undertones, are there ways to accent to tone down the coolness of the gray? Thanks!
