It's Color. Only Better. Day-Glo Color Corp. is the world's largest manufacturer of daylight fluorescent pigments. We develop technologies that improve and enhance any color, from subtle specialty effects, to glow-in-the-dark pigments, to our classic range of fluorescents. We're proud of our heritage and the role our fluorescents played in pop culture history. From the days of disco to punk rock and pop-art posters to graffiti on the Berlin wall - no matter the trend, no matter the event, Day-Glo was there, making things brighter, bolder, and so much cooler! But there's a lot more to Day-Glo than just fluorescents. With our extensive technical expertise and diversified product lines, Day-Glo has served the world's color marketplace since the 1930's. At Day-Glo, we make colors better - richer reds, brighter oranges, deeper greens, and even colors that glow in the dark! Discover for yourself our custom color solutions for packaging and consumer goods, plastics, graphic arts, paints and coatings, dyes and textiles, as well as the personal care and cosmetics ingredients industries. Day-Glo was founded in 1946 by Bob and Joe Switzer, who originally experimented with certain dyes and resins that produced bright colors that had the unique effect of glowing under ultraviolet light. These unique effects were originally used in magic shows and theater. As the chemistry and manufacturing process improved, the areas of application expanded. In 1991 Day-Glo was purchased by its current owner, RPM, Inc., a worldwide producer of coatings, sealants and specialty chemicals. Today Day-Glo's technology has continued to grow and the company has developed products for many other industries including security pigments, and consumer products.
