There are about 250 fluorescent brighteners listed by the [British] Society of Dyers and Colourists and the American Association of Textile Chemists and Colorists in the third edition of the Colour Index (CI), of which only 27 are commercially available today. They are listed, along with their CI number, chemical class, application (e.g., cellulose, nylon, paper, protein fibers) and properties (e.g., fastness to chlorine, peroxide and light).

This Colour Index list shows what a great variety of brighteners there are, each with its own capabilities and drawbacks. Most of them fluoresce colors: yellow, bright blue, greenish blue, bluish violet, reddish blue, greenish yellow, bright reddish violet. These must be what give "Day-Glo" colors their eye appeal (or shock value), and brighten ordinary colors in both textiles and papers. A few fluoresce white or "neutral"; these must be the brighteners used in laundry soaps and white paper.
