Cobalt was called months ago, back when the forecasts for the season landed and everyone quietly started saving pictures of electric blue coats. The prediction held. Our feeds have gone properly blue this summer, in every register from a saturated  blue Klein to something icy and barely there. The plot twist arrives in what sits beside it. Black has been quietly retired from the job of anchoring a bright blue, and brown has stepped in with a softer, warmer kind of contrast that flatters the color instead of flattening it.

Reach instead for brown and blue stripes, this season’s answer to the Breton, worn with white denim or a tobacco linen trouser. Layer several blues over a caramel base for something that looks accidental in the most expensive way. Painters figured this out long before the runways did, since umber counts among the oldest pigments we have, with a name that some trace to the Latin word for shadow, while cobalt arrived in 1802 courtesy of a French chemist tasked with inventing an affordable stand-in for ultramarine. Van Gogh reached for it whenever he needed a sky. Two centuries later, the same conversation between earth and pigment is happening on your body, an
