infinity, 3, or 7

There are an infinite number of frequencies of light in a rainbow. Color, however, is interpreted by our eyes. Our eyes have four different types of receptors, three for the primary colors and one for black and white. So in a way there are only three colors in a rainbow. People commonly divide the colors of a rainbow into an acronym ROYGBIV; red, orange, yellow, green, blue, indigo, and violet.
