Contrasting colours - green/orange

Ornge & blue, a photo by caroline..collins1 on Flickr.

f/22 55mm 1/60 ISO1600
This is an image of my cat. The image was taken outdoors to take advantage of natural light. I used a small aperture of f/22. I cropped the image down to use the eyes and nose to create an implied triangle. The saturation of the colour was increased slightly to improve the green of the eyes and orange of the nose.
