In September 1985, the Nalco Chemical Company of Oak Brook purchased Day-Glo Color for approximately $40 million. [10] They then sold it to RPM International in 1991 for an undisclosed price. In 2012, Day-Glo Color Corp. was recognized as a National Historic Chemical Landmark for its development of daylight fluorescent pigments. [11]
Luminous ink under ultraviolet light Fluorescent paintings lit by black light. Black light paint or black light fluorescent paint is luminous paint that glows under a black light. It is based on pigments that respond to light in the ultraviolet segment of the electromagnetic spectrum. The paint may or may not be colorful under ordinary light.
DayGlo fluorescent pigments, developed by Bob Switzer and Joe Switzer of Switzer Brothers, Inc., (now Day-Glo Color Corp.) between the 1930s and 1950s [70] Rachel Carson's book Silent Spring , published in 1962 [ 71 ]
Switzer was co-inventor of the first black light fluorescent paint along with his brother Joseph Switzer and the inventor of the Magnaglo process for nondestructive flaw-detection in machined parts.

Fluorescent security strip in a US twenty dollar bill under UV light. Strongly fluorescent pigments often have an unusual appearance which is often described colloquially as a "neon color" (originally "day-glo" in the late 1960s, early 1970s).

Invisible fluorescent paints ...

Biliproteins found in plants and algae serve as a system of pigments whose purpose is to detect and absorb light needed for photosynthesis. The absorption spectra of biliproteins complements that of other photosynthetic pigments such as chlorophyll or carotene. [3]
