The 1970s palette is having a real moment again, and the trick to making it feel like 2026 rather than a rerun is restraint. This scheme leads with a rich Burnt Orange and pairs it with a muted Avocado Green, the two shades that define the whole era.
A wide base of Soft Cream keeps things from going heavy, while Golden Mustard adds a sunny middle note that bridges the orange and the green. Walnut Brown is the grounding accent, the wood-tone depth that makes the warmer colors glow instead of shout.
Use the orange as your hero, keep the green and mustard supporting, and let the cream carry most of the space. Done that way, this reads cozy and collected, with just enough vintage charm to feel deliberate.
