I've found it before on philosophical book covers, on the Berlin U-Bahn (scroll about half way down), on necklaces and always inspired by the vibrant combinations the excellent Out of the Dark team come up with.
Above, if strong shades scare you – putting a rich colour against the right neutral background keeps things muted yet striking. This denim blue and biscuit-y wall get along famously don't you think? The backdrop really brings out the brightness of the sofa. And that yellow book suggests a good cushion or accessory colour if you're after a zingier palette still.
And bolder still...
But if understated is way more your thing, give natural tones a sharp edge with strong accents: black does a very good job, and I like the green grasses here too, giving taupes, ropes and beiges a sand-dune vibe.
