Interesting. You could have described the color as a shade of chocolate or even earth, which makes me wonder if you're unhappy with the color and might want to change it before thinking about pillows. In any case, in order to truly picture this color, we probably need to know what kind of cow...

Rowe Furniture has very clean line sofas that I think would be an appropriate scale for this room. LOVE the red feature wall. You do need to bring the red into the room but knowing how you want the room to feel can help determine a color palette. If you want the room to have energy and "pop", try a split-complementary or triadic color scheme. If you want it to be more relaxed and harmonious, I would suggest an analogous color scheme.

Walls r light pink bt wants to paint them beige in near future. There r two long doors at both ends of narrow ( 7.7ft. x 14 ft. ) living area .am thinking of either maroon or dull golden color for the curtain .is it okay ??

Reupholstering furniture is expensive. Do you think Red + Mustard or olive would be okay ? Should i add neutral colors in the place surrounding the sofas (like rugs, curtains, wall pieces) to minimize loudness? I'd flip this around. Go with neutral furniture - - bring color and texture in with area rugs, draperies, accent pieces...
