Trend colours versus timeless colours
How to tell what lasts from what is gone in five years
A Pantone Colour of the Year on the walls looks dated in six months. Truly timeless colours, by contrast, cross decades without a wrinkle.
§ 01The principle
A colour is timeless when it has survived at least three aesthetic cycles (approximately 60 to 80 years) without falling from favour. A colour is trendy when it appears massively in the design press, "colour of the year" cards, and Instagram accounts over a two-to-five-year period.
This is not a matter of taste, it is a matter of probability. A recently mass-adopted shade statistically has a high chance of being dated in five years. A shade present in interiors for fifty years has an equal chance of remaining there for another fifty.
The mistake is not loving millennial pink, sage green or mocha mousse. The mistake is putting them on 60% of the walls in a flat you own for twenty years.
Timeless = in the press for fifty years · Trendy = in the press for five years
The test of time is not opinion, it is data.
§ 02Putting it into practice
The practical rule, called the 80/20 trend rule.
80% timeless shades on large surfaces (walls, ceilings, large furniture, rugs). This is the solid base that will not age. For walls: off-whites, warm beiges, taupes, deep greens (sage, forest), deep blues (teal, navy), mid terracotta.
20% trend touches on small, easily changed elements. Cushions, a throw, a small decorative object, perhaps a wall in a secondary room you repaint every five years. Here, trends are fair game, because the investment is low and the change is quick.
To identify whether a shade is timeless: search for it in interior design books from the 1970s, 1990s, and 2010s. If it is present in all three decades, it is timeless. If it appears only in one of them, it is probably cyclic.
- 01Reserve the 80% base for colours with proven longevity
- 02Apply trends only to easily replaced elements
- 03Test a "trend" shade in a secondary room before committing to the living room
- 04Verify any shade's longevity by cross-referencing it across thirty years of archives
- 01Painting a large living room in the Pantone colour of the year
- 02Investing in a trend-coloured sofa when you keep sofas for ten years
- 03Confusing "I like it now" with "I will like it in 2035"
- 04Eliminating all trend touches, which makes an interior sterile
§ 03Professional variations
Jean-Louis Deniot never works with trend colours on walls or large furniture. He builds his palette entirely from timeless shades, then adds a single contemporary touch: a recent artwork, a cushion in a current shade. The architecture breathes thirty years, the detail breathes the current season.
India Mahdavi takes a different approach: she reinterprets timeless codes in unexpected combinations. Her pink is not millennial pink, it is a powder pink with a rosy pigment that can be found in 1940s interiors. She positions herself between timeless and trend, which gives her a singular aesthetic.
Timeless on the walls, trends on the cushions.
