I have received multiple asks confused about how Lexa doesn’t have grey looking skin if her blood is black. I am probably going to bore or lose most of you as I try to explain human anatomy. lol. (also most of this knowledge is from my High School Anatomy class so…yeah…take from that what you will.)
How your eyes see color is what is REFLECTED off of an object. In a ray of light there are multiple colors of visible light. Think of a prism and how it splits light into a rainbow of colors: red, orange, yellow, green, blue, indigo, violet. These wave lengths HIT an object and some colors are absorbed and some are reflected. Your eyes pick up on the wavelengths that aren’t absorbed, but are REFLECTED. The rods and cones in your eyes read these wavelengths and your brain interprets them. Therefore, an object that you think is red is due to the object ‘absorbing’ the other rays of light and NOT absorbing the red wavelength. The red wavelength bounces off of the object and into your eye and your brain ONLY reads that red wavelength – making you conclude the object is red.
Inside your blood there are red blood cells, white blood cells, platelets, and plasma. Red blood cells carry oxygen throughout the body; white blood cells fight infections; platelets stop bleeding when a person is cut; and plasma is the liquid that carries nutrients, hormones, and proteins throughout the body. Blood inside your body is naturally a red color. But the severity of the red is dependent on how much oxygen your red blood cells are carrying. When they are on their way to deliver oxygen to cells, they are a brighter red color. After they have delivered oxygen to the cells, they become a darker red color. When you are cut, your blood becomes SATURATED with oxygen and turns a bright vibrant red color. However, after awhile, it loses it’s bright red color as it de-oxygenates. Your platelets also start getting to work to coagulating your blood to stop the bleeding.
So, I think that this ‘mutagen’ is another ‘substance’ inside the Nightblood’s blood OR it is somehow attached to the platelets ‘engaging’ mechanism; mechanism that once the blood becomes saturated with oxygen it engages. But, it is always in the bloodstream. The mutagen, like platelets, are always in the blood stream…even when they are dormant. So, this is how the Nightbloods are able to stave off ALIE – it is constantly in their blood. But, it turns black when it is SATURATED with oxygen when a person is cut.
In a normal person, when they are cut, their blood looks red due to the blood absorbing all light wavelength colors BESIDES red and bounces the red wavelength back at your eyes. This ‘mutagen’, when it is is SATURATED by oxygen, ABSORBS the red wavelength as well as the rest. Therefore, your brain interprets the blood as black.
In conclusion, Lexa and the other Nightbloods have normal visibly looking and functioning blood, UNTIL it is SATURATED by oxygen and exposed directly to light. This mutagen doesn’t change the color of blood when it is inside the body. The mutagen, when it is saturated, absorbs the red wavelength of light that is normally reflected off of blood. When all wavelengths of light are absorbed, your brain interprets that color as black.
I hope this helps explain things. This is of course my theory, but this is how it would medically make sense to me. Also, we have to remember that this is a Sci-Fi show and it is loosely based on science. But, the above explanation makes the most sense to me.
i really like how i asked ppl to ask me about my characters and immediately everyone wanted to know more about dear leander. despite being the most beautiful person on earth he doesn’t know how to take compliments and gets easily flustered. here.
“So I’m talking about way back; like, 1180, that’s when Robin was doing his thing. He was like an Earl; he was proper posh; he was also like a man of the people. All the birds would love him. I mean, they loved him. He was like an olden-day David Beckham. Men wanted to be him, women wanted to fuck him, and that was Robin Hood.”

Poe Dameron gets on his knees for the Resistance and definitely doesn’t think about Finn while he does it; Finn might be a little bit worried about him but he certainly isn’t jealous
Please thank @cicaklah for the tag “Poe Dameron: Battle slut of the Resistance” which inspired this fic. Because you know, last time I wrote something restrained and dignified, this time I had to lower the tone with a Stormtroopers Made Then Do It story.
