South Feng Shui for living room?

Looking to redecorate this spring, and incorporating Feng Shui principles ( for the first time ).. My living room is the only south room, and according to this should be predominantly red. Problem is none of my exhisting furnishings go, and I can't afford to replace them. The living room also has a direct east, and west wall, which green, and gold both would go well. Can I do an accent wall say on the west wall in a gold tone, and incorporate red accents like vases or art?
