For trail graphics, let Burnt Orange carry route numbers in a denser version of the same heat. Signs feel less aggressive when their cooler sections use Air Force Blue.
California has enough weight for outdoor notices, event dates, and trail markers. It reads quickly from a distance but needs generous neutral space when several messages share one board.
California can carry a poster date or wayfinding arrow without an outline. Against white it feels sunny; against tan it becomes more earthen.
