Horizon Blue Metallic

Horizon Blue Metallic (Horizontblau Metallic, code 37X) is a soft, medium-depth blue metallic at #5C7B9D — a composed, silver-inflected blue that reads as neither particularly dark nor brilliantly saturated, occupying the considered, grown-up part of the blue spectrum where elegance takes precedence over drama. It has enough grey in its base to flatten the blue just slightly, giving it the horizontal, expansive quality suggested by its name. Rennbow documents it on the 911 in 1991–1993 and again in 2006–2007, and on the 928 from 1991 to 1995 and the 968 from 1992 to 1994 — a cross-model presence across the water-cooled transition era. The colour was rare enough on the 928 that forum research has found only a handful of US-market examples, with the 928 registry showing very few confirmed cars in Horizon Blue for any year. Seven documented community examples in the database, the majority from the 911 where it was more broadly available, confirm it as a selectively ordered colour in both production windows.
