List of Warriors characters
The "Warriors" novel series is written by Erin Hunter. Due to the large number of characters present in the novel series, this list is divided by Clan, e.g., all characters in ThunderClan are listed together. Each cat has a prefix. Eg: Dawn, Violet etc. As a young kit they will have -kit at the end of their name. Eg: Dawnkit Violetkit. When they are an apprentice -paw will be at the end of their name. Eg: Dawnpaw Violetpaw. When that cat is a warrior or medicine cat they will have a suffix. Eg: -fur -pelt -cloud -flame -wing -song etc. Eg: Dawnsong Violetflame. That is if they are in one of the clans like ThunderClan, RiverClan, WindClan, ShadowClan, Skyclan.
North Nicosia
North Nicosia or Northern Nicosia ( ) is the capital and largest city of the "de facto" state of Turkish Republic of Northern Cyprus. It is the northern part of the divided city of Nicosia and is governed by the Nicosia Turkish Municipality. , North Nicosia had a population of 61,378 and a metropolitan area with a population of 82,539. Following the intercommunal violence of the 1960s, the capital of Republic of Cyprus was divided between the island's Greek Cypriot and Turkish Cypriot communities in the south and north respectively in 1963. A coup by the Greek military junta in an attempt to unite the island with Greece in 1974 led to the Turkish invasion of Cyprus, and the international community considers North Nicosia to have been under Turkish occupation since then.
Eye color
Eye color is a polygenic phenotypic character determined by two distinct factors: the pigmentation of the eye's iris and the frequency-dependence of the scattering of light by the turbid medium in the stroma of the iris. In humans, the pigmentation of the iris varies from light brown to black, depending on the concentration of melanin in the iris pigment epithelium (located on the back of the iris), the melanin content within the iris stroma (located at the front of the iris), and the cellular density of the stroma. The appearance of blue and green, as well as hazel eyes, results from the Tyndall scattering of light in the stroma, a phenomenon similar to that which accounts for the blueness of the sky called Rayleigh scattering.
Blue
Blue is one of the three primary colours of pigments in painting and traditional colour theory, as well as in the RGB colour model. It lies between violet and green on the spectrum of visible light. The eye perceives blue when observing light with a dominant wavelength between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colors; azure contains some green, while ultramarine contains some violet. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called Tyndall scattering explains blue eyes.
List of Monster High characters
Mattel's fashion doll franchise "Monster High" features a variety of fictional characters, many of whom are students at the titular high school. The female characters are classified as Ghouls and the male characters are classified as Mansters. The characters are generally the sons and daughters, or related to monsters that have been popularized in fiction. The franchise's official website identifies six of the characters as Original Ghouls. In addition to the listed Ghouls and Mansters, there are other characters who have been introduced in the franchise's related media including the web/video and book series.
List of Ben 10 aliens
This is a list of aliens on Cartoon Network's "Ben 10 franchise". Voiced by:  Heatblast is a Pyronite from the star Pyros. He appears as a magma-based lifeform whose body is composed of a bright inner magma body covered by a reddish-brown charcoal-like crust. Heatblast is essentially "living magma", thus everything he touches either melts or catches fire. In the original series, he is the tenth alien in the Omnitrix. Heatblast is Ben's first transformation, accidentally activated and started a wildfire in the pilot episode of the original series, "And Then There Were 10" when Ben was trying to remove the Omnitrix immediately after it first attached to him.
Champagne gene
The champagne gene is a simple dominant allele responsible for a number of rare horse coat colors. The most distinctive traits of horses with the champagne gene are the hazel eyes and pinkish, freckled skin, which are bright blue and bright pink at birth, respectively. The coat color is also affected: any hairs that would have been red are gold, and any hairs that would have been black are chocolate brown. If a horse inherits the champagne gene from either or both parents, a coat that would otherwise be chestnut is instead gold champagne, with bay corresponding to amber champagne, seal brown to sable champagne, and black to classic champagne.

I agree. Especially blue eyes that are almost aqua.

Apparently the blue-green appearance occurs from the Tyndall scattering of light in the stroma of the eye.

Tyndall effect
The Tyndall effect, also known as Willis–Tyndall scattering, is light scattering by particles in a colloid or else particles in a very fine suspension. It is named after the 19th-century physicist John Tyndall. It is similar to Rayleigh scattering, in that the intensity of the scattered light depends on the fourth power of the frequency, so blue light is scattered much more strongly than red light. An example in everyday life is the blue colour sometimes seen in the smoke emitted by motorcycles, in particular two-stroke machines where the burnt engine oil provides these particles. Under the Tyndall effect, the longer-wavelength light is more transmitted while the shorter-wavelength light is more reflected via scattering.
Iris (anatomy)
The iris (plural: irides or irises) is a thin, circular structure in the eye, responsible for controlling the diameter and size of the pupil and thus the amount of light reaching the retina. Eye color is defined by that of the iris. In optical terms, the pupil is the eye's aperture, while the iris is the diaphragm. The iris consists of two layers: the front pigmented known as a stroma and, beneath the stroma, pigmented epithelial cells. The stroma connects to a sphincter muscle (sphincter pupillae), which contracts the pupil in a circular motion, and a set of dilator muscles (dilator pupillae) which pull the iris radially to enlarge the pupil, pulling it in folds.

Chloroplast
Chloroplasts are organelles, specialized compartments, in plant and algal cells. Their discovery inside plant cells is usually credited to Julius von Sachs (1832–1897), an influential botanist and author of standard botanical textbooks – sometimes called "The Father of Plant Physiology". The main role of chloroplasts is to conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the energy from sunlight and converts it and stores it in the energy-storage molecules ATP and NADPH while freeing oxygen from water. They then use the ATP and NADPH to make organic molecules from carbon dioxide in a process known as the Calvin cycle.
John Tyndall (politician)
John Hutchyns Tyndall (14 July 193419 July 2005) was a British fascist political activist. A leading member of various small neo-Nazi groups during the late 1950s and 1960s, he was chairman of the National Front from 1972 to 1974 and again from 1975 to 1980, and then chairman of the British National Party from 1982 to 1999. He unsuccessfully stood for election to the House of Commons and European Parliament on several occasions. Born in Devon and educated in Kent, Tyndall undertook national service prior to embracing the extreme-right. In the mid-1950s, he joined the League of Empire Loyalists (LEL) and came under the influence of its leader, Arthur Chesterton.
Stroma, Scotland
Stroma is an island off the northern coast of the mainland of Scotland. It is the most southerly of the islands in the Pentland Firth between the Orkney islands and Caithness, the northeasternmost part of the mainland. The name is from the Old Norse "Straumr-øy" meaning "island in the [tidal] stream". Ancient stone structures testify to the presence of Stroma's earliest residents, while a Norse presence around 900–1,000 years ago is recorded in the "Orkneyinga Saga". It has been politically united with Caithness since at least the 15th century. Although Stroma lies only a few miles off the Scottish coast, the savage weather and ferociously strong tides of the Pentland Firth meant that the island's inhabitants were very isolated, causing them to be largely self-sufficient, trading agricultural produce and fish with the mainlanders.

Really? I never knew that. So it's just a trick of light...
