Hemospectrum

In Awakening Rift, the Hemospectrum is a series of blood colors possessed by the trolls of Kraisa. Similar to Homestuck, it is the basis of the Kraisonian caste system. Lusii share these blood colors, or always have the same blood color as their charge. The caste, in order, goes as such. With red sitting at the bottom of the hemospectrum and fuchsia sitting at the highest end of the homospectrum.

Biology
Depending on the troll's blood color, there are several biological consequences that follow the social consequences of the caste system. A troll's blood can saturate into their gums, sweat, tongues, and tears, but in a more diluted color. These blood colors are also found within Lusii, which in turn take care of a troll with the shared blood color. Other features include the survival abilities that most lowbloods have, chucklevoodoos possessed by purplebloods, and the aquatic and amphibious nature possessed by trolls within the Violet and Fuchsia castes such as facial fins and gills that physically differ them from the rest.

Lifespan and population
Commonly, the higher the blood caste, the higher the lifespan of it and the lower the population it has. For example, rustbloods usually live through a dozen or two sweeps, while the highest of castes live through hundreds of them or even thousands. Exceptions to this rule are lime, jade, and fuschiabloods, due to their societal rules or rarity of lusii available for them, respectively. However, there can be exceptions that can either lengthen or shorten a troll's life.

Sea dwellers
Sea dwellers are two of the most rarest castes on Kraisa, both on the brink of extinction and only making up .001% of the populaition. Sea dwellers are unique in the way that they live in the sea or nearby similar bodies of water, and rarity compared to other high castes. They are also considered high royalty.

Blood mutations
Blood mutations are any blood color that seemingly cannot fit within Kraisa's hemospectrum, or any of it's intermediary colors between castes. With mutations in bloodcolor can possibly be accompanied by mutations in physical strength or psychic abilities.

Social aspects
The social hierarchy on Kraisa is based on an individuals blood color.

It is speculated that the caste system works similarly to the medieval class systems on Earth.

Going off this speculation, one can assume that this makes rustbloods peasantry, bronzebloods near-peasantry, and the social climb goes up from there. Looking from the top of the class down, purplebloods would be mid to high royalty, while bluebloods would be nobility. Jade and tealbloods are hard to discern due to the fact that both their castes are within the middle of the hemospectrum, and their ranks could swing both ways. Usually, they have caste-specific duties to fulfill unlike the others of its kind.

Hemotyping
Hemotyping is a tradition in troll society of which a troll uses their blood color for writing and appearing as the color of their symbol. All of the trolls shown in Awakening Rift practice hemotyping.

Rustblood
Red Blood, also stated as Rust Blood, is the lowest blood caste within the Hemospectrum.

Bronzeblood
Bronze Blood is the second-lowest blood caste.

Goldblood
Gold Blood is the third-lowest blood caste.

Limeblood
Lime Blood is a very rare and one of a kind "caste" that exists outside of the hemospectrum. Only one troll of of shared blood is currently alive.

Oliveblood
Olive Blood is the fourth-lowest blood caste.

Jadeblood
Jade Blood is the fifth-lowest blood caste, similar to limebloods, the numbers of trolls on Kraisa within this caste are scarce. Due to their rarity, they are under federal protection by the Court, and are considered pseudo-royalty, keeping to jobs underground for tending to the Mother Grub and keeping her well.

Tealblood
Teal Blood is the upmost middle blood caste.

Blueblood
Blue Blood is the fifth-highest blood caste.

Indigoblood
Indoigo Blood is the fourth-highest blood caste.

Purpleblood
Purple Blood is the third-highest blood caste.

Violetblood
Violet Blood is the fifth-highest blood caste. And similar to Jadebloods, they are a rare caste that are kept under federal protection, however keeping their status as royalty.

Fuchsiablood
Fuchsia Blood is the utmost highest blood caste. It is still considered a caste despite being succeeded by only one troll. This is out of respect for the many that went extinct during the darker ages of history. This caste, to this day is still one of the rarest blood castes, on the brink of extinction. The same can be said for the violet caste, save for the slightly larger population the caste possesses.

Unknown/Mutants
Unknowns, more commonly known as Mutants, are those who do not fit into any caste on the hemospectrum or anything in between. They can fit into the lime or fuchsia caste, but may still be classified as a Mutant. The process varies by the individual.

Trivia

 * Alliya Arjuna played a large role in the development of the modern hemospectrum and the subcategories of each caste.
 * Most of the blood colors are roughly divided at 30° - 40° on the HSV/HSL color system. However the Lime and Olive castes have the smallest division, sitting at 75°-89°.
