TrailBlue is a Garmin watch face designed for trail runners and outdoor athletes, featuring three signature elements that highlight Garmin's unique sensor capabilities. -- BODY BATTERY SILHOUETTE Your body's energy reserve, visualized as a rainbow-filled human figure. The fill rises from feet (purple) up through legs (red), waist (yellow), torso (green) to head (blue) as Body Battery increases. When Body Battery drops to 19% or below, the silhouette outline pulses red as a warning. -- 24-HOUR SUN SCALE RING The outer ring shows a full day at a glance: * Night : deep navy * Dawn : purple to amber gradient * Day : warm gold * Dusk : red to purple gradient A sun icon (during daylight) or moon with current phase (at night) marks where you are in the cycle. Sunrise and sunset positions are immediately readable. -- TIME-REACTIVE BACKGROUND The face background subtly shifts color with the time of day, amplifying the sun scale's awareness without overwhelming the foreground.
