Color trends are some of the fastest-moving in design. A shade can be all the rage one month and forgotten the next. Even though 2025 was billed as the year of the anti-trend, it felt like more colors than usual had their moment in the spotlight. From cherry reds and burgundies to buttery yellows, chocolate browns, and refreshing teals, certain shades captured our attention – but which ones are starting to feel dated?

We spoke with interior designers and color experts to find out which once-popular color trends are losing their appeal in 2026, and why.
