Color

Color (American English) or colour (Commonwealth English) is the visual perceptual property corresponding in humans to the categories called red, blue, yellow, etc. 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 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.

The science of color is sometimes called chromatics, 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).

Tincture (heraldry)

In heraldry, tinctures are the colours used to emblazon a coat of arms. These can be divided into several categories including light tinctures called metals, dark tinctures called colours, nonstandard colours called stains, patterns called furs, and "proper". A charge described as proper (also sometimes termed "natural") is coloured as it would be found in nature.

Use of tinctures

One of the few fundamental rules of heraldry is that metals must not be placed upon other metals and colours must not be placed upon other colours, while furs and proper can sometimes be placed upon either or both. This is referred to as the rule of tincture.

Nonstandard colours called stains were introduced in the late Middle Ages, but have largely been shunned as contrary to the heraldic spirit of bold images and bright, contrasting colours. A peculiar fad of the Renaissance sought to couple each tincture with an associated planet, gemstone, flower, astrological sign, etc., but this practice was soon abandoned and is now regarded as wildly divergent from the science of heraldry. The 19th century saw the rise of "landscape heraldry" and extensive use of charges tinctured "proper", especially in augmentations (and more often in German heraldry than English), but this practice too has been deprecated as essentially unheraldic.

Timbre

In music, timbre (/ˈtæmbər/ TAM-bər or /ˈtɪmbər/ TIM-bər) also known as tone color or tone quality from psychoacoustics, is the quality of a musical note, sound, or tone that distinguishes different types of sound production, such as voices and musical instruments, string instruments, wind instruments, and percussion instruments. The physical characteristics of sound that determine the perception of timbre include spectrum and envelope.

In simple terms, timbre is what makes a particular musical sound different from another, even when they have the same pitch and loudness. For instance, it is the difference between a guitar and a piano playing the same note at the same loudness. Experienced musicians are able to distinguish between different instruments of the same type based on their varied timbres, even if those instruments are playing notes at the same pitch and loudness.

Synonyms

Tone quality and color are synonyms for timbre, as well as the "texture attributed to a single instrument". Hermann von Helmholtz used the German Klangfarbe (tone color), and John Tyndall proposed an English translation, clangtint, but both terms were disapproved of by Alexander Ellis, who also discredits register and color for their pre-existing English meanings (Erickson 1975, 7).

List of Bionicle characters

Bionicle characters consist of the various species and races that exist in the fictional universe of Lego's franchise Bionicle.

The universe is mostly inhabited by beings with a skeletal and muscular structure, but metallic armor rather than skin. Most beings' skulls are bare, and they wear Kanohi Masks, of which some enable psychokinetic feats.

The Matoran Universe

Matoran

The Matoran are a race of small humanoid beings, and the most common inhabitants of their namesake universe. A few become Toa at some point in their lives; but in their natural state, their elemental energies manifest as minor physical enhancements, and they cannot activate the powers of Kanohi Masks. Though they are among the weakest races, they will fight to the last for their homes and lives, and are able to create fortresses, weapons, defense machines, and whatever other tools they need. The Matoran live by the principles of Unity, Duty, and Destiny. All Water, Lightning, & Psionics Matoran are female; all others, with the exception of Light and Shadow, are male. Both Light and Shadow are mix-gender. Light Matoran, more commonly known as Av-Matoran, can change the colour of their armour and channel power through their weapons. Certain Matoran such as Fe-Matoran of iron and De-Matoran of sonics, have been reduced in number by the Brotherhood of Makuta.

Battlefield 2142

Battlefield 2142 is a first-person shooter video game developed by EA DICE and published by Electronic Arts. It is the fourth game in the Battlefield series. Battlefield 2142 is set in the 22nd century, during a new ice age which sees two military superpowers – the European Union (EU) and Pan Asian Coalition (PAC) – battle for the remaining land.

The game was designed primarily for multiplayer gameplay and allows for a maximum of 64 players on a server or a maximum of 16 players in single player mode against bots on Conquest mode. It has its own ranking system to keep track of the user's statistics similar to the one used in its predecessor, Battlefield 2. It opens up new categories of vehicles and weapons not seen in Battlefield 2. Battlefield 2142 has an unlock system that allows the player to choose a new unlock every time they achieve a new rank instead of forcing the player to purchase items. A booster pack called Northern Strike contains new maps, unlocks, and vehicles; a deluxe edition was released that contains Battlefield 2142 and Northern Strike.
