to be detected by inspecting the parts under black light. After a dispute with
Continental Lithograph over the rights to Zyglo and Magnaglo, the brothers established the independent Switzer Brothers, Inc. in 1946 to continue developing and marketing new uses for fluorescent materials. The company changed its name to Day-Glo Color Corp. in 1969.
242:
In 1938, they invented Zyglo and
Magnaglo, two flaw-detection processes using fluorescent dyes. The dyes are suspended in fluids which emphasize defects in parts (by penetrant action in the case of Zyglo and by the attraction of magnetic particles in the case of Magnaglo), both allowing the defects

In the 1940s, the company began developing a new class of pigments that fluoresced in daylight by converting ultraviolet light to visible light, resulting in brighter colors than other types of pigments. These daylight fluorescing pigments are also known as DayGlo.

For its annual DayGlo Show, Day-Glo donates its paint to artists in
Northeast Ohio who use it to create original two- and three-dimensional art that is displayed in a gallery lighted with UV light (black light).

The brothers established the Fluor-S-Art Co. in 1934 to develop and sell black light paints for advertising purposes. They later partnered with
Continental Lithograph (a subsidiary of
