...and it's "dramatically provocative" and communicates "originality, ingenuity and visionary thinking." What could it be?
It's ultra violet (or Pantone 18-3838), which Leatrice Eiseman, executive director of the Pantone Colour Institute describes as: "a blue-based purple that takes our awareness and potential to another level."
There are other changes coming this year to on-trade interior design trends too, says Michael Sinclair, design director at the Catering Design Group.
He points to a shift from the "warehouse phase" to the use of fresher, more natural décor, inspired by California and Scandinavia (think clear glass lights bouncing off pale wood furniture, he says).
It's also good bye to Edison bulbs and cage shades in favour of LED bulbs, giving not only a superior lifetime but also upping a site's eco credentials. In terms of furniture, two distinct themes will emerge this year, he forecasts.
"The metallic hues of gold and bronze remain en vogue and the leaning towards fresh and natural, will take these choices further, as we see an upsurge in the use of polished nickel and silver in furniture.
"Interestingly, the second most prevalent theme on the rise is the contrasting 'Bake-Off' home-style, with its muted pastels, pale wood and shabby chic groupings of varying colours within the same cluster.
"This echoes the ongoing desire among many consumers for a simpler way of life - think pastel seats, accented with elements of burnt brown and oranges, offset by grey or hints of blue."
