Cottonwood Leaves, New Zealand

Photograph by Bill Hatcher

Yellow evokes the shine of the sun and is found throughout nature and the man-made world as a color that commands attention. This highly visible hue is found on everything from bumblebees to school buses, traffic signs to highlighters. Misbehaving soccer players are shown yellow as a warning, and Tour de France racers know the man in yellow is the rider to beat.

Here, cottonwood leaves drift on clear water in New Zealand. The country’s landscape includes forests, mountains, fjords, and pastures.
