Magenta () is a colour that is variously defined as purplish-red, reddish-purple or mauvish-crimson. On colour wheels of the RGB (additive) and CMY (subtractive) colour models, it is located exactly midway between red and blue. It is one of the four colours of ink used in colour printing by an inkjet printer, along with yellow, black, and cyan, to make all other colours. The tone of magenta used in printing is called "printer's magenta".
Magenta took its name from an aniline dye made and patented in 1859 by the French chemist François-Emmanuel Verguin, who originally called it fuchsine. It was renamed to celebrate the Italian-French victory at the Battle of Magenta fought between the French and Austrians on June 4, 1859, near the Italian town of Magenta in Lombardy. A virtually identical colour, called roseine, was created in 1860 by two British chemists: Chambers Nicolson and George Maule.
The web colour magenta is also called fuchsia.

The Royal Institution of Great Britain (often the Royal Institution, abbreviated 'Ri' or 'RI') is an organisation for scientific education and research, based in the City of Westminster. It was founded in 1799 by the leading British scientists of the age, including Henry Cavendish and its first president, George Finch, the 9th Earl of Winchilsea. Its foundational principles were diffusing the knowledge of, and facilitating the general introduction of, useful mechanical inventions and improvements, as well as enhancing the application of science to the common purposes of life (including through teaching, courses of philosophical lectures, and experiments).
Much of the Institution's initial funding and the initial proposal for its founding were given by the Society for Bettering the Conditions and Improving the Comforts of the Poor, under the guidance of philanthropist Sir Thomas Bernard and American-born British scientist Sir Benjamin Thompson, Count Rumford. Since its founding it has been based at 21 Albemarle Street in Mayfair. Its Royal Charter was granted in 1800.
