About Food coloring
Wikipedia Article About Food coloring on Wikipedia

People learn to associate certain colors with certain flavors, and this causes the color of food to influence the perceived flavor, in anything from fruit gums to wine [1] For this reason, food manufacturers add dyes to their products. Sometimes the aim is to simulate a natural color as perceived by the consumer, such as adding red coloring to glacé cherries (which would otherwise be beige), but sometimes it is for effect, like the green ketchup that Heinz launched in 2000.

The American food industry uses 3000 tons of food color per year.

While most consumers are aware that foods with bright, unnatural colors, like Froot Loops, are artificially colored, few people know that apparently "natural" foods such as oranges are sometimes also dyed to mask natural variations in color. Most trust the regulation of their governments to keep any unsafe additives off the market, but there is a vigorous public debate about the safety of many food colorings - a notable example being tartrazine. A growing minority believes that the effects of colorings have not been well enough researched and consider their use an unnecessary risk.
