Fortaleza (Portuguese pronunciation: [foʁtaˈlezɐ], Fortress) is the state capital of Ceará, located in Northeastern Brazil. With a population close to 2.3 million (metropolitan region over 3.4 million), Fortaleza is the 5th largest city in Brazil. It has an area of 313 square kilometres (121 sq mi) and the highest demographic density in the country (8,001 per km²). To the north of the city lies the Atlantic Ocean; to the south are the municipalities of Pacatuba, Eusébio, Maracanaú and Itaitinga; to the east is the municipality of Aquiraz and the Atlantic Ocean; and to the west is the municipality of Caucaia. Residents of the city are known as Fortalezenses. The current mayor is Roberto Cláudio, a doctor graduated at the Federal University of Ceará. Fortaleza is one of the three leading cities in the Northeast region together with Recife and Salvador. The city will be one of the host cities of the 2014 FIFA World Cup, for which Brazil is the host nation.
A facade or façade (pron.: /fəˈsɑːd/) is generally one exterior side of a building, usually, but not always, the front. The word comes from the French language, literally meaning "frontage" or "face".
In architecture, the façade of a building is often the most important from a design standpoint, as it sets the tone for the rest of the building. Many façades are historic, and local zoning regulations or other laws greatly restrict or even forbid their alteration.
Color or colour (see spelling differences) is the visual perceptual property corresponding in humans to the categories called red, blue, yellow, green and others. Color derives from the spectrum of light (distribution of light power versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. Color categories and physical specifications of color are also associated with objects, materials, light sources, etc., 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.
The science of color is sometimes called chromatics, chromatography, colorimetry, or simply color science. It includes the perception of color by the human eye and brain, the origin of color in materials, color theory in art, and the physics of electromagnetic radiation in the visible range (that is, what we commonly refer to simply as light).
