Of late, I often see images on the news showing the stock index board either a sea of red or mostly green. Red when the bears command, and green when the bulls charge. What would a color blind see on the stock index board?

According to Wikipedia: a color blind is a person or animal unable to distinguish between two or more primary colors (usually red and green)

This leads me to wonder if not being a color blind is a prerequisite to become a remisier.
