Chrominance

Chrominance (chroma or C for short) is the signal used in video systems to convey the color information of the picture, separately from the accompanying luma signal (or Y for short). Chrominance is usually represented as two color-difference components: U = B′ − Y′ (blue − luma) and V = R′ − Y′ (red − luma). Each of these difference components may have scale factors and offsets applied to it, as specified by the applicable video standard.

In composite video signals, the U and V signals modulate a color subcarrier signal, and the result is referred to as the chrominance signal; the phase and amplitude of this modulated chrominance signal correspond approximately to the hue and saturation of the color. In digital-video and still-image color spaces such as Y′CbCr, the luma and chrominance components are digital sample values.

Separating RGB color signals into luma and chrominance allows the bandwidth of each to be determined separately. Typically, the chrominance bandwidth is reduced in analog composite video by reducing the bandwidth of a modulated color subcarrier, and in digital systems by chroma subsampling.

Chroma: A Queer Literary Journal

Chroma was a UK-based international literary and arts journal publishing and promoting the work of lesbian, gay, bisexual and transgender writers and artists. It was founded in 2004. The journal appeared twice a year and was supported by funding from Arts Council England. The journal was edited by the writer, Shaun Levin, and the poet, Saradha Soobrayen, and had four commissioning editors, András Gerevich, Sophie Mayer, Andrew Theophilou, and Mike Upton. Some of the queer writers that was featured included Ben Barton, John Dixon, Jay Merill, Keith Munro, Uriel Orlow, Drew Payne, Mima Simic and Andrew Warburton. The journal also held an annual writing competition. The journal's last issue (No 11) was published in June 2010. An announcement on the journal's website explains that changes in funding arrangements with the Arts Council of England meant the journal would "take a break" in Autumn 2010 and return in Spring 2011 with a youth number. This issue did not appear.
