Everyone should see black, green, gray, and orange-brown in the image. Otherwise, posting about an off-color, out of focus image ADDS NOTHING to this discussion.
Examining coins out in the "wild" is often done under poor lighting conditions. I advise everyone to practice viewing coins in good and poor environments using several different types of light including sunlight. Furthermore, I suggest folks have their vision checked. Many collectors, especially men, suffer from color blindness making it hard to see changes of color.
For added points on the quiz: What does the color green indicate on copper coins?
