An interior design trend born out of a viral TikTok video, championing the addition of red "in places where it has no business", is the focus of our latest lookbook.
The "unexpected red theory" was coined by Brooklyn-based interior designer Taylor Migliazzo Simon in a video that has had over 900,000 views on TikTok.
Simon describes it as "adding anything that's red, big or small, to a room where it doesn't match at all" with the result that "it automatically looks better".
The theory suggests that red is as versatile as a neutral colour because it can work in almost any palette of colours and materials, either as an accent or complementary tone.
Here, we look at 10 home and hotel interiors that show how it's done, either in the form of architectural fittings and finishes like a balustrade or floor surface or in the form of statement furniture. This is the latest in our lookbooks series, which provides visual inspiration from Dezeen's archive. For more inspiration see previous lookbooks featuring homes with indoor slides, colourful renovations and innovative New York City lofts.
