Updating your property? Avoid these outdated colour schemes for 2026

Interior designers say several once-popular colour schemes are becoming outdated in 2026, with the shift moving away from saturated or overused tones. According to Homes & Gardens, colour trends are “some of the fastest-moving in design,” making it essential for homeowners who are regularly redecorating their holiday or long-term rentals.

The move aligns with broader styling changes already identified across the continent. Recent Euro Weekly News coverage, such as how Venetian influence is shaping modern Spanish interiors, highlights a clear return to subtle, timeless craftsmanship over louder visual statements.

Forest greens and sage tones losing appeal in 2026

Greens have dominated interior palettes for years, but designers say the most ubiquitous shades are now falling out of favour. Homes & Gardens cites Los Angeles designer Jessica Nicastro, “Forest green is going out of style for 2026 – it has been done so much.” Washington D.C. designer Hannah Goldberg echoes this, noting that pale sage and deep forest greens have become “overdone” and that “people are feeling a bit tired of them.”

This trend is reinforced by Real Simple, which reports that sage green has “peaked after years of oversaturation on walls, cabinets and textiles.”

A modern alternative is an in-between blue and green, teal.

Mustard and butter yellow fall out of favour

Mustard yellow, a standout of the 1970s revival, is also firmly on the “dated” list for 2026. Homes & Gardens quotes designer Kristina Khersonsky, who says the colour “has had its moment” but is now “overused and overproduced”, appearing in mass-market décor and furniture.

Other major publications agree. Martha Stewart Living recently predicted that butter and sunny yellows will feel outdated in the coming year as homeowners gravitate towards more richer golds and ochres.

Artificial and highly saturated tones lose their place

A third category being phased out includes synthetic-looking colours such as bright tomato reds, sugary lilacs, bubblegum pinks, and other “laboratory” shades. As fabric designer Bernie de Le Cuona told Homes & Gardens, “Artificial colours are starting to feel out… these shades can feel harsh and fleeting.”

Designers from New York-based Kobel + Co add that over-pigmented brights often appear “flat or overly graphic” and lack the depth sought in contemporary interiors.

This shift aligns with emerging design directions identified at Feria Hábitat Valencia 2025, one of Spain’s major design fairs, where earthy palettes, natural textures and Mediterranean-rooted tones dominated exhibitor collections for 2026.

The colours that interior designers recommend for 2026

Across major interior publications, clear preferences are emerging:

✔ Earthy palettes

Elle Decor highlights 2026’s move towards “warmer, richer neutrals”, including tobacco brown, dusty olive, and terracotta.

✔ Jewel tones

Deep sapphire, muted emerald and cranberry red offer sophistication without overwhelming a room.

✔ Warm base colours

Cool greys and stark whites are being replaced by softer creams, greige blends and warm porcelains, creating more welcoming interiors.

For those choosing colours to redecorate their holiday homes or long-term rentals, picking shades that are current but also long-lasting can influence:

• Resale and rental appeal, especially important for investment properties.
• Comfort in sunnier climates – Mediterranean light is far more flattering to earthy, warm tones than to pasty greys or stark whites.
• Cost and longevity, as avoiding short-lived trends reduces the need for frequent repainting.
• Better synergy with traditional Spanish architecture, which often features stone, terracotta and warm finishes.
