I’ve updated and improved my Hemospectrum chart! I added more colors and adjusted a few of the hues so that they’re closer to the canon hue. I’ve also added a few notes on some colors denoting which ones are rarer or extinct. Mutant colors are no longer quite as vibrant but of course still very much off the normal chart of the 70 to 90 grade tones.
Here are my original posts regarding the Hemospectrum: This one delves into each caste while this one talks a little more about my personal headcanons.
This chart is also uploaded to my DeviantArt for those that might be interested.
