International Colour Day
International Colour Day is an annual event held on March 21 to celebrate colour. The day was established by the International Colour Association (abbreviated as ''AIC'' for its French name, ), which is composed of national colour organizations and members representing over 30 countries. Background The adoption of a worldwide day of colour was first proposed in 2008 by the Portuguese Color Association, whose president, Maria Joao Durao, presented the idea to the International Colour Association (abbreviated as ''AIC'' for its French name, ). The proposal was agreed upon in 2009 among the members of the AIC, which is composed of national colour organizations and members representing over 30 countries. International Colour Day was thereby established, with the 21st of March adopted as the official date. This date was chosen because it is around the equinox, when "the sun shines directly on the equator," and thus, the duration of day and night are approximately equal in length aro ...

Colour
Color (American English) or colour (British English) is the visual perceptual property deriving from the spectrum of light interacting with the photoreceptor cells of the eyes. Color categories and physical specifications of color are associated with objects or materials based on their physical properties such as light absorption, reflection, or emission spectra. By defining a color space, colors can be identified numerically by their coordinates. Because perception of color stems from the varying spectral sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantified by the degree to which they stimulate these cells. These physical or physiological quantifications of color, however, do not fully explain the psychophysical perception of color appearance. Color science includes the perception of color by the eye and brain, the origin of color in materials, color theory in art, and the physics of electr ...

Rainbow
A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the Sun. Rainbows can be full circles. However, the observer normally sees only an arc formed by illuminated droplets above the ground, and centered on a line from the Sun to the observer's eye. In a primary rainbow, the arc shows red on the outer part and violet on the inner side. This rainbow is caused by light being refracted when entering a droplet of water, then reflected inside on the back of the droplet and refracted again when leaving it. In a double rainbow, a second arc is seen outside the primary arc, and has the order of its colours reversed, with red on the inner side of the arc. This is caused by the light being reflected twice on the inside of the drop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Inter-Society Color Council
The Inter-Society Color Council (ISCC) is a non-profit learned society which was created in 1931 to advance the understanding and application of visual color as it relates to science, industry, and art. The Council also serves to coordinate between different organizations in the United States for which color plays a major role (for example, design, printing, or computer graphics). The Council is composed of individual members and Sustaining Members, and supplies the United States' representatives to the International Commission on Illumination. The society maintains three Interest Groups to provide focus for presentations at conferences. The Interest Groups are ''Fundamental and Applied Color Research'', ''Industrial Applications of Color'', and ''Art, Design, and Psychology''. Journal The Council endorses the international journal ''Color Research and Application'' and encourages the submission of such reports and articles to this journal for consideration for publication.

University Of Zagreb
The University of Zagreb ( hr, Sveučilište u Zagrebu, ; la, Universitas Studiorum Zagrabiensis) is the largest Croatian university and the oldest continuously operating university in the area covering Central Europe south of Vienna and all of Southeastern Europe. The University of Zagreb and the University North are the only public universities operating in Northern and Central Croatia. The history of the University began on September 23, 1669, when the Holy Roman Emperor Leopold I issued a decree granting the establishment of the ''Jesuit Academy of the Royal Free City of Zagreb''. The decree was accepted at the Council of the Croatian Kingdom on November 3, 1671. The Academy was run by the Jesuits for more than a century until the order was dissolved by Pope Clement XIV in 1773. In 1776, Empress Maria Theresa issued a decree founding the ''Royal Academy of Science'' which succeeded the previous Jesuit Academy. Bishop Josip Juraj Strossmayer proposed the founding of a Univ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Light
Light or visible light is electromagnetic radiation that can be perceived by the human eye. Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths). In physics, the term "light" may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not. In this sense, gamma rays, X-rays, microwaves and radio waves are also light. The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum and polarization. Its speed in a vacuum, 299 792 458 metres a second (m/s), is one of the fundamental constants of nature. Like all types of electromagnetic radiation, visible light propagates by massless elementary particles called photons that represents the quanta of electromagnetic field, and can be analyzed as both waves and par ...
