Glo Brite Floss is commonly used to provide strike points and create bright attractive heads. The original fluoro range is devised by Tom Saville and is available in large 100yd spools and a range of numbered colours which makes finding the correct colour much easier. Most fly tying manuals refer to these colours by number.
