Blue Team

Blue Team can represent several things:

Blue

Blue is the colour between violet and green on the optical spectrum of visible light. Human eyes perceive blue when observing light with a wavelength between 450 and 495 nanometres. Blues with a higher frequency and thus a shorter wavelength gradually look more violet, while those with a lower frequency and a longer wavelength gradually appear more green. Pure blue, in the middle, has a wavelength of 470 nanometres. In painting and traditional colour theory, blue is one of the three primary colours of pigments, along with red and yellow, which can be mixed to form a wide gamut of colours. Red and blue mixed together form violet, blue and yellow together form green. Blue is also a primary colour in the RGB colour model, used to create all the colours on the screen of a television or computer monitor.

The modern English word blue comes from Middle English bleu or blewe, from the Old French bleu, a word of Germanic origin, related to the Old High German word blao. The clear sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. When sunlight passes through the atmosphere, the blue wavelengths are scattered more widely by the oxygen and nitrogen molecules, and more blue comes to our eyes. Rayleigh scattering also explains blue eyes; there is no blue pigment in blue eyes. Distant objects appear more blue because of another optical effect called atmospheric perspective.

Halo 4

Halo 4 is a 2012 first-person shooter video game developed by 343 Industries and published by Microsoft Studios for the Xbox 360 video game console. The seventh video game installment in the Halo franchise, the game was released worldwide in November 2012. Halo 4's story follows a cybernetically enhanced human supersoldier, Master Chief, and his artificial intelligence construct Cortana, as they encounter unknown threats while exploring an ancient civilization's planet. The player assumes the role of Master Chief, who battles against rogue remnants of the military alliance of alien races known as the Covenant and warriors of the Forerunner empire known as the Prometheans. The game features a selection of weapons, enemies, and game modes not present in previous titles of the series.

Development of Halo 4 began in 2009 and continued until September 2012. Halo 4 is 343 Industries' first original title within the Halo series—previously, development of the main series was undertaken by Bungie, the creator of the franchise. In the developmental process, 343 Industries decided to explore the Forerunner fiction within the Halo universe, leading the team to design a new setting, enemies, and main antagonist. Existing characters and assets received visual overhauls and motion capture was used for animation within cutscenes. A goal for Halo 4's story was to incorporate more human elements; to achieve this, the developers chose to delve more deeply into the relationship between the two protagonists, Master Chief and Cortana. Several external studios assisted 343 Industries with developing Halo 4, and over 350 people worked on the game in total.

Red vs. Blue

Red vs. Blue, often abbreviated as RvB, is an American comic science fiction video web series created by Burnie Burns with his production company Rooster Teeth Productions. The show is distributed through the Internet on Rooster Teeth's website, as well as on DVD, Blu-ray, and is syndicated through the El Rey Network. The story centers on two opposing teams of soldiers fighting a civil war in the middle of a desolate box canyon (Blood Gulch), in a parody of first-person shooter (FPS) games, military life, and science fiction films. Initially intended to be a short series of six to eight episodes, the project quickly and unexpectedly achieved significant popularity following its Internet premiere on April 1, 2003. The series consists of thirteen canonical seasons and five mini-series. Red vs. Blue is the longest running episodic web series.

Red vs. Blue emerged from Burnie Burns' voice-over-enhanced gameplay videos of Bungie Studios' FPS video game Halo: Combat Evolved. The series is primarily produced using the machinima technique of synchronizing video footage from a game to pre-recorded dialogue and other audio. Footage is mostly from the multiplayer modes of Halo: Combat Evolved and its sequels, Halo 2, Halo 3, and Halo 4, along with its prequel, Halo: Reach, and Halo 3 ODST on the Xbox and Xbox 360 video game consoles.
