Blue rose

A blue rose is a flower of the genus Rosa (family Rosaceae) that presents blue-to-violet pigmentation instead of the more common red, white, or yellow. Blue roses are often portrayed in literature and art as a symbol of love and prosperity to those who seek it, but as a result of genetic limitations do not exist in nature. White roses have been dyed blue. In 2004, researchers used genetic modification to create roses that contain the blue pigment delphinidin.

So-called "blue roses" have been bred by conventional hybridization methods, but the results, such as "Blue Moon", are more accurately described as being lilac in color.

Dyed roses

Since blue roses do not exist in nature, as roses lack the specific gene that has the ability to produce a "true blue" color, blue roses are traditionally created by dyeing white roses. In a book entitled Kitab al-felahah written by Ibn al-‘Awwām al-Ishbīlī in Arabic in the 12th century, and translated into French by J. J. Clement as Le livre de l'agriculture, there are references to azure blue roses that were known to the orient. These blue roses were made by placing a blue dye into the bark of the roots.

Rose

A rose (/ˈroʊz/) is a woody perennial flowering plant of the genus Rosa, in the family Rosaceae. There are over 100 species and thousands of cultivars. They form a group of plants that can be erect shrubs, climbing or trailing with stems that are often armed with sharp prickles. Flowers vary in size and shape and are usually large and showy, in colours ranging from white through yellows and reds. Most species are native to Asia, with smaller numbers native to Europe, North America, and northwest Africa. Species, cultivars and hybrids are all widely grown for their beauty and often are fragrant. Rose plants range in size from compact, miniature roses, to climbers that can reach seven meters in height. Different species hybridize easily, and this has been used in the development of the wide range of garden roses.

The name rose comes from French, itself from Latin rosa, which was perhaps borrowed from Oscan, from Greek ρόδον rhódon (Aeolic βρόδον wródon), itself borrowed from Old Persian wrd- (wurdi), related to Avestan varəδa, Sogdian ward, Parthian wâr.

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.

Soundtrack

A soundtrack, also written sound track, can be recorded music accompanying and synchronized to the images of a motion picture, book, television program or video game; a commercially released soundtrack album of music as featured in the soundtrack of a film or TV show; or the physical area of a film that contains the synchronized recorded sound.

Origin of the term

In movie industry terminology usage, a sound track is an audio recording created or used in film production or post-production. Initially the dialogue, sound effects, and music in a film each has its own separate track (dialogue track, sound effects track, and music track), and these are mixed together to make what is called the composite track, which is heard in the film. A dubbing track is often later created when films are dubbed into another language. This is also known as a M & E track (music and effects) containing all sound elements minus dialogue which is then supplied by the foreign distributor in the native language of its territory.

Steven Universe

Steven Universe is an American animated television series created by Rebecca Sugar for Cartoon Network. It is the coming-of-age story of a young boy named Steven, who grows up in the town of Beach City living with three magical humanoid aliens, the "Crystal Gems" Garnet, Amethyst, and Pearl. Steven, who is half-Gem, goes on adventures with his friends and helps the Gems protect the world from their own kind. Sugar developed the series while working as a storyboard artist on Adventure Time, and it premiered on November 4, 2013 as Cartoon Network's first series to be created by a woman.

The series has received critical acclaim, being praised for its art design, music, voice acting, and complex characterization and science-fiction worldbuilding. It was nominated for an Emmy Award and five Annie Awards. Steven Universe was renewed for a third season in 2015. Companion books, comics, and a video game based on it have also been released.
