Magenta is a color between purple and red, evoked by lights with less power in yellowish-green wavelengths than in blue and red wavelengths (complements of magenta have wavelength 500–530 nm).[1] It is an extra-spectral color, meaning it cannot be generated by a single wavelength of light. The name magenta comes from the dye magenta, commonly called fuchsine, discovered shortly after the 1859 Battle of Magenta near Magenta, Italy.
In the Munsell color system, magenta is called red-purple. In the CMYK color model used in printing, it is one of the primary colors of ink. In the RGB color model, the secondary color created by mixing the red and blue primaries is called magenta or fuchsia, though this color differs in hue from printer’s magenta.
Art
- Since the mid 1960s, water based fluorescent magenta paint has been available to paint psychedelic black light paintings. (Fluorescent magenta is one of the seven main colors used, in addition to fluorescent orange, fluorescent red, fluorescent cerise, fluorescent chartreuse yellow, fluorescent blue, and fluorescent green.)
- By the early 1960s, vivid colors in the magenta range became available, and as a result many become aware that magenta, yellow, and cyan make better primary pigments than red, blue, and yellow.
Parapsychology
- To psychics who claim to be able to observe the aura with their third eye, someone who has a magenta aura is usually described as being artistic and creative. It is reported that typical occupations for someone with a magenta aura would be such professions as artist, art dealer, actor, author, costume designer, or set designer.[4]
Cryptography
n cryptography, MAGENTA is a symmetric key block cipher developed by Michael Jacobson Jr. and Klaus Huber for Deutsche Telekom. The name MAGENTA is an acronym for Multifunctional Algorithm for General-purpose Encryption and Network Telecommunication Applications. (The color magenta is also part of the corporate identity of Deutsche Telekom.) The cipher was submitted to the Advanced Encryption Standard process, but did not advance beyond the first round; cryptographic weaknesses were discovered and it was found to be one of the slower ciphers submitted [1].
MAGENTA has a block size of 128 bits and key sizes of 128, 192 and 256 bits. It is a Feistel cipher with six or eight rounds.
After the presentation of the cipher at the first AES conference, several cryptographers immediately found vulnerabilities [2]. These were written up and presented at the second AES conference (Biham et al, 1999).
