What is day glo?

Day-Glo is a brand of fluorescent and neon colors that are extremely bright and vivid. The colors are created by adding fluorescent pigments to ink, paint, or plastic materials. The brand was founded in 1935 by Robert Switzer, who discovered the fluorescent pigments while working on a safer and more efficient alternative to the black lights commonly used in movie theaters at the time. Today, Day-Glo colors are used in a variety of applications, from safety clothing and signage to fashion, art, and entertainment. The bright and bold colors have become a popular symbol of youth culture and the rave scene.
