Blue.

A close-up, eye-level shot shows a big blue heron gliding over a body of water. The heron is flying from the upper-left to the upper-right. It has a long, gray neck with a black and white face that extends into a yellow beak. The feathers closer to its neck are a light-blue, and the feathers beneath are a mixture of dark-blue and black. Its long, black legs are trailing right behind it. The water is an almost-glowing blue and stretches the whole background. It has ripples crossing to make the water seem like it is at an angle.
