More troll bio shit
Mar. 18th, 2013 11:17 amPigments found in trolls:
1. Hemospectral pigments. These are probably not responsible for the carrying of oxygen through the bloodstream; they're additive substances, comparable to the bile pigments in a Prasinohaema skink. They are canonically known to discharged from a troll's system in bodily fluids such as sweat and tears.
2. A pigment ranging from yellow-orange to red-orange in coloration. Hussie has confirmed that troll schlera and troll horns have the same pigmentation. It appears that when troll eyes become more heavily stressed, they become a deeper, redder shade of orange - possibly due to a chemical reaction with some substance in a troll's blood? In art team contributions, it also is found on a troll's fingernails and toenails.
3. A black pigment. This appears in the hair, and also a troll's lips. The distribution may be similar to the distribution of red pheomelanin in humans - densest in not only the hair and lips, but also freckles, genitals, and nipples (if your headcanon trolls have nipples).
4. A lighter pigment, possibly chalky white or light grey, that in conjunction with black pigment allows for the opaque grey coloration of troll skin. Reflecting light and heat instead of absorbing it, it probably acts as a much more effective sunscreen for Beforan and Alternian species than the black pigment that sufffices in Earth animals does.
