A Blue Monkey standing on a branch in an evergreen forest

Waves of iridescent clouds erupt in pastel colors at sunset

Young friends laughing at their snow man died blue with food dye

A piece of dead seaweed floating through dappled sunlight in the ocean

The wolf-like stare of a Siberian Husky sled dog with very blue eyes
