Cobalt blue is set to be the hottest colour trend for autumn/winter 2026, with high street retailers already stocking the vibrant hue. The shade has been spotted at fashion weeks in London, Paris, Milan and Copenhagen, and is now filtering into the latest launches from M&S, Next and Nobody's Child.
The Trend
Unlike softer trends like butter yellow and chocolate brown, cobalt blue is bold and unapologetic, designed to stand out. It dominated collections from luxury labels including Victoria Beckham and Jil Sander, and now fashion enthusiasts can tap into the trend on a budget.
However, cobalt blue isn't universally flattering. With cool undertones and a highly saturated finish, it tends to suit cooler complexions and higher contrast colouring. Those with warmer or softer colouring may find it overpowering, but can still wear it through accessories and shoes.
