We usually link the color blue to calmness, coolness, passivity, and having a levelheaded outlook. Fluorescent blue, however, represents calm yet dynamic energy.

Fluorescent compounds such as ninhydrin or DFO (1,8-Diazafluoren-9-one) later became useful in forensics, particularly when searching for fingerprints. Today, fluorescent reagents, like fluorescein, are being used to find blood and other substances. Fluorescent Colors: Psychology and Meaning

Bone-margin detection: Alizarin-stained specimens and certain fossils can be lit by fluorescent lights to view anatomical structures, including bone margins. [84]Pantone TPX Pantone Color Finder—Type the words "Vista Blue" into the indicated window on the Pantone Color Finder and the color will appear: Azure ( / ˈ æ ʒ ər, ˈ eɪ ʒ ər/ AZH-ər, AY-zhər, UK also / ˈ æ z jʊər, ˈ eɪ z jʊər/ AZ-ure, AY-zure) [30] [31] [32] is a variation of blue that is often described as the color of the sky on a clear day. Type the words "Silver Lake Blue" into the indicated window on the Pantone Color Finder and the color will appear. This color was first discovered by Inventor Georges Claude in 1910 by adapting Moore Lamps to use noble gases, in this case, the noble gas neon. 2. Fluorescent Orange

The polka-dot tree frog ( Hypsiboas punctatus), widely found in South America, was unintentionally discovered to be the first fluorescent amphibian in 2017. The fluorescence was traced to a new compound found in the lymph and skin glands. [48] The main fluorescent compound is Hyloin-L1 and it gives a blue-green glow when exposed to violet or ultraviolet light. The scientists behind the discovery suggested that the fluorescence can be used for communication. They speculated that fluorescence possibly is relatively widespread among frogs. [49] Only a few months later, fluorescence was discovered in the closely related Hypsiboas atlanticus. Because it is linked to secretions from skin glands, they can also leave fluorescent markings on surfaces where they have been. [50] Mäthger, L. M.; Denton, E. J. (2001).

The color fluorescent blue with hexadecimal color code #15f4ee is a shade of cyan. In the RGB color model #15f4ee is comprised of 8.24% red, 95.69% green and 93.33% blue. In the HSL color space #15f4ee has a hue of 178° (degrees), 91% saturation and 52% lightness. This color has an approximate wavelength of 492.47 nm. Bony fishes living in shallow water generally have good color vision due to their living in a colorful environment. Thus, in shallow-water fishes, red, orange, and green fluorescence most likely serves as a means of communication with conspecifics, especially given the great phenotypic variance of the phenomenon. [29] The earliest discovery of a fluorescent effect was first discovered in 1560 and 1565 by Bernardino de Sahagún and Nicolás Monardes, respectively. This fluorescent effect came in the form of a matlaline chemical compound infusion taken from the wood of two tree species, Pterocarpus indicus, and Eysenhardtia polystachya . Swallowtail ( Papilio) butterflies have complex systems for emitting fluorescent light. Their wings contain pigment-infused crystals that provide directed fluorescent light. These crystals function to produce fluorescent light best when they absorb radiance from sky-blue light (wavelength about 420nm). The wavelengths of light that the butterflies see the best correspond to the absorbance of the crystals in the butterfly's wings. This likely functions to enhance the capacity for signaling.

Fluorescent Blue Trellis Pattern

Many plants are fluorescent due to the presence of chlorophyll, which is probably the most widely-distributed fluorescent molecule, producing red emission under a range of excitation wavelengths. [59] This attribute of chlorophyll is commonly used by ecologists to measure photosynthetic efficiency. [60]

In some cases, the concentration of the activator must be restricted to below a certain level, to prevent quenching of the fluorescent emission. Furthermore, the mineral must be free of impurities such as iron or copper, to prevent quenching of possible fluorescence. Divalent manganese, in concentrations of up to several percent, is responsible for the red or orange fluorescence of calcite, the green fluorescence of willemite, the yellow fluorescence of esperite, and the orange fluorescence of wollastonite and clinohedrite. Hexavalent uranium, in the form of the uranyl cation ( UO 2+ While our eyes can see millions of colors, these colors usually fall under just a few fluorescent versions. As of writing this article, there are currently only 7 different fluorescent colors. Fluorescence in fluorites was described by both Edward D. Clarke in 1819 and René Just Haüy in 1822. The same phenomenon was also observed in chlorophyll by Sir David Brewster in 1833 and Sir John Herschel in 1845.
