As noted before, trolls can vary quite a bit from one another on the outside Turns out, that same level of variance occurs on the inside too! This difference can be classified using something called the hemospectrum.
The hemospecturm is the spectrum of all the different blood color a troll could possess, excluding mutations. The color of virtually all bodily fluids, such as tears, are also determined by the blood color. The hemospectrum sees use as both a social caste system and a biological classification.
The classes are as follows:
The hemospectrum ranges the color spectrum, utilizing twelve classes to group up sections.
The different blood colors occur based upon the oxygen binding process their body is built to employ, something likely adapted to make different environments more tenable, using a combination of methods rather than just the one.
Akin to the hemospectrum itself, most biological differences in the castes are a range, with one point being the lowest end of the hemospectrum, rust, and the other the highest point, fuchsia. For the sake of comparison, let's look at these two polarized ends to pose the differences.
Commonality: Rust bloods are as common as rocks. You walk outside, there's rust bloods. You go to a different planet, there's rust bloods. They are everywhere. Which is probably good given their turnover rate is historically rather high. By comparison, fuchsia bloods would be considered rather rare, usually only one fuchsia blood being spawned for every twelve redbloods.
Body Temperature: Moving from rust up to fuchsia, body temperature drops significantly. A rust blood is quite warm to the touch, like a walking, talking, portable furnace. A rust blood's body has to work pretty hard to maintain their high body temperature, which leads to them needing more nutrients more often and easily over stressing. Alternatively, fuchsia bloods have moderately low body base temperatures, cool to touch and verging into chilly for some. Fuchsia bloods have rather advanced biological mechanisms to maintain the necessary cool in hotter weather, making external temperatures a relatively low tax on their bodies.
Natural Ability: Rust bloods, as may have already been established, are pretty average. To be clear, they are not weak, but when compared to a fuchsia? Yes, they pale quite a bit in comparison. From rust moving up, trolls of higher castes are gifted with increasing physical strength and durability. Skin gets thicker, bone get denser, and other mild improvements that make higher bloods sturdier and stronger.
Sensitivities: Rust bloods, as the lowest caste, have rather delicate sensibilities when it comes to certain matters. Subsonic noises, psionic disturbances, temperature, allergies. Most things, in all honesty, the rust blood will experience more harshly. Moving up the hemospectrum, the sensitivities decrease. That isn't to say that a fuchsia blood doesn't experience temperature change per say, but that to them, it's a more dulled experience, something of little note. Similarly, they may have trouble picking up psionic interference. Not out of not being able to sense it, but because it's like white noise, where for a rust blood it may be akin to shrill alarms. A fuchsia must focus and pay attention to the sensation where for a rust it is likely overwhelming or painful.
It is concluded from these differences that higher blood castes are more evolved and advanced forms of the troll species. It is very likely that the rust blood came first and the higher blood castes were adaptations and evolution from there, but that would be a rather controversial statement we don't recommend making in public.
