So me and oneirogenic worked on a Hemospectrum chart for our own reference and I figured I’d make it presentable and share it. So okay, here’s the details: 
This is, from my perspective, the best way to have slight variation in troll blood colors, with still keeping to canon. Hussie says there are 12 blood colors, including Lime. Then you have Karkat as a 13th, mutant blood color. There are technically 12 colors + potential mutant variations listed here. There are just different shades.
MOST of the Troll’s marked colors were taken from comic panels. However, some were shifted slightly warmer or cooler so the spectrum would actually function more like, well, a spectrum. Not to mention the fact that the blood colors of the trolls do change between different panels (which is expected). So think of them as close-as-possible estimates.
Sollux’s blood color, for example, is technically cooler than is shown here, and Nepeta’s is technically very slightly warmer, however, in order to fit in Lime Bloods, I had to shift theirs very slightly in different directions.
Since the canon blood colors we have to work off of fell into a specific range, that’s where we marked off the spectrum for color picking. All of the trolls easily fell into the lightest lights, the mid range, or the darkest darks. Because the hue of each Troll’s blood color fell neatly in this selected range, but many had different shades, I decided to set this up with the three steps for three possible shades of each hue.
So that’s why I have three shades of each color. I like to think that trolls would only have the 12 basic colors, but depending on the troll itself, your colors vary slightly between light or dark.
The mutant blood colors are taken from each color in the spectrum, and shifted to the highest saturation, like Karkat’s. No clue if these colors could exist in canon, but I stuck them in anyway to balance the chart. You probably don’t wanna give your Fantroll mutant blood, though.
Dots obviously mark where each Troll fits into this chart. And that’s about it! Other than that, I had a lot of fun making this because I love colors. And now I’m gonna use this to make all of the fantrolls. All of them.
