Not only is there a paint shade that you must avoid, but there’s also an overused trend that you’ll need to wave goodbye too.

Posting on social media, Loren Kreiss, an Interior and Furniture Designer from the US, shared his expert take on the trends that are worth trying and those you may want to ditch.

The CEO and Creative Director of Kreiss, a luxury furniture company, said: “Interior design trends for 2026 and beyond – here’s what’s in and here’s what’s out.”

First things first, according to Loren, an in trend is painting your walls, ceiling and trim the same neutral colour.

He explained: “It’s been the standard for top interior designers for years and it’s finally time for you to get on board.”

Therefore, on the out is having a white ceiling and trim, as Loren added: “It’s giving grandma and looks sloppy and unpolished.”

Not only this, but as per Loren’s advice, in are the “new neutrals.”

He revealed: “Taupes, ivories and creams are leading the warm neutral revolution. It’s time for a cream dream.”

But if you want to avoid an eyesore, according to this guru, you’ll need to ditch green. 

Loren shared: “Out – green, it might just be the new millennial grey.

“Avocado cream is everywhere and it’s the stuff of nightmares.”

Instead of using green paint, Loren advised using midtone browns, such as chocolate and walnut shades, which he believes are “rich, classic and just plain yummy.”

As well as this, Loren also likes “natural, timeless design philosophies” such as quiet luxury and warm minimalism.

To this, he explained: “They’re so ancient they’re contemporary and never go out of style.”

But you’ll need to make sure you avoid “cheesy 2010 design fads,” which according to Loren, include “white shaker cabinets, modern farmhouse and sad millennial grey colour palettes,” which he claimed will “make a mockery of your home.”

Trends interior designers hate

IF you want to ensure that your home looks glam, here are the trends that interior designers can’t stand.

NO YELLOW: According to Bilal Rehman, yellow paint in a bedroom is a big no no.

He said: “If you want everyone to know you’re a horse girl then yellow is perfect for you.”

SIGN OFF: Kelly Hoppen shared her honest thoughts on Live, Love, Laugh signs.

The interior pro explained: “Another gripe of mine – Live, Laugh, Love – those kinds of wooden things that sit on book shelves and floating shelves, that’s so 10, 12, 15 years ago.”

NO GREY YAY: Julie Provenzano explained that grey interiors have been overdone.

She stressed: “We took a good thing and we overdid it to the point that it now feels copy, paste, basic.”

Finally, as 2026 fast approaches, if you want a home that’s Loren-approved, you’ll want to think about waving goodbye to “ fussy, functionless gimmicks like decorative crown moulding, pot fillers, man caves and especially the frame TV.”

To this, Loren concluded: “They’re an absolute abomination.”
