If you have a classic colour palette that you never tire of, just do touch-ups as required. For other colour schemes—if, for example, you choose a neutral colour for hallways—you may only need to paint a room or two (or only an accent wall) every three to four years. As for updates, keep your space fresh by adding new accessories or just moving around existing ones. Sometimes simply rearranging your furniture makes your place feel new!
