Genoa  /ˈdʒɛnoʊ.ə/ (Italian: Genova [ˈdʒɛːnova] ( listen); Genoese and Ligurian Zena [ˈzeːna]; Latin and, archaically, English Genua) is the capital of Liguria and the sixth largest city in Italy, with a population of 608,676 within its administrative limits on a land area of 243.6 km² (94 sq mi). The urban zone of Genoa extends beyond the administrative city limits with a population of 718,896. The urban area of Genoa has a population of 800,709. In the metropolitan area live between 859,000 and 1.4 million or 1.5 million people. Genoa is one of Europe's largest cities on the Mediterranean Sea and the largest seaport in Italy.

Italy ⁱ/ˈɪtəli/ (Italian: Italia [iˈtaːlja]), officially the Italian Republic or the Republic of Italy (Italian: Repubblica italiana), is a unitary parliamentary republic in south-central Europe. To the north, it borders France, Switzerland, Austria and Slovenia along the Alps. To the south, it consists of the entirety of the Italian Peninsula, Sicily, Sardinia–the two largest islands in the Mediterranean Sea–and many other smaller islands. The independent states of San Marino and the Vatican City are enclaves within Italy, whilst Campione d'Italia is an Italian exclave in Switzerland. The territory of Italy covers some 301,338 km² (116,347 sq mi) and is influenced by a temperate seasonal climate. With 60.6 million inhabitants, it is the fifth most populous country in Europe, and the 23rd most populous in the world.

Color or colour (see spelling differences) is the visual perceptual property corresponding in humans to the categories called red, green, blue, 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).

Liguria (pronounced [liˈɡuːrja], Ligurian: Ligûria) is a coastal region of north-western Italy, the third smallest of the Italian regions. Its capital is Genoa. It is a popular region with tourists for its beautiful beaches, picturesque little towns, and good food.
