As a BNHA fan, I have spent an inordinate amount of time trying to figure out why Mina’s skin is bright pink.

And like many other BNHA fans who rationalise everything a little too much, I am a strong believer in the “secondary mutations” quirk theory, which I’ll explain in another post, but I have also come up with a less believable but more interesting theory.

In chemistry, phenolphthalein is used as an acid indicator; meaning, it gets put in liquids to cause a colour change depending on the liquid’s pH so that scientists can tell whether or not something is acidic.

As far as you’ll learn in grade 10 chemistry (which is as far as I got before deciding I was more of an art kid), when phenolphthalein is mixed with a basic substance, it turns pink. When it’s mixed with a neutral substance, it is generally faint pink/colourless. When it is mixed with an acid, it is colourless (chemistry-speak for clear).

(Image: photos arranged in order of low pH to high pH. High pH liquid is the most pink, as explained in the paragraph above.)

How does this relate to Mina’s skin?

To determine that, it’s best to start with Mina’s acid. It’s colourless (the art style depicts it as a milky-white, but it could just as easily be clear; also, phenolphthalein doesn’t change the colour of an acid, it only changes its own colour, so yeah). Therefore, since it is acid and has a low pH, it stands to reason that it could contain phenolphthalein and still remain colourless.

Mina’s skin, on the other hand, is not acidic as far as we know . It would actually make sense for her skin to be a bit basic to counteract her quirk, so her skin still protects her from her own acid (because basic and acidic substances neutralise each other). So if her skin contained phenolphthalein, it stands to reason that her skin would have a pink-like hue. In that sense, it’s actually quite cool that her skin is pink; it implies that her quirk has an inbuilt indicator to tell her when her skin isn’t basic enough to protect her properly, and when her acid is no longer acidic. Could she also create basic substances, rather than just acid? Is that why her acid contains phenolphthalein? Who knows!

Does this theory have a shit ton of holes? Yes. Is it likely that Horikoshi made the active decision to make Mina’s skin pink to hint at a second aspect of her quirk as an indicator? Nah, he’s too misogynistic to pay close attention to a girl’s character design like that. But it’s fun to think about. Chemistry is cool.

Phenolphthalein, for example, changes a solution from colourless to pink as the pH of the solution changes over a range of 8.2 to 10.0 (see table 11.9).

Phenolphthalein is therefore a nearly perfect indicator for the titration of a weak acid by a strong base, where the pH at the equivalence point is on the basic side (figure 11.19).

Bromocresol green (BCG) is a dye that is used in chemistry and analytical chemistry as a pH indicator in acid-base titration and in thin-layer chromatography staining solutions to visualize acidic compounds. Generally, the indicator can be prepared by dissolving BCG in an ethanol solution.

Idk if y'all have ever found out that not only is it possible to be partially color blind (anomalous trichromacy) but also that you are partially color blind in the middle of a chemistry lab but it's NOT FUN.

The colour we then observe is that of the base form of the indicator (figure 11.24).

Ooh what's that neon pink liquid over there for?

That is Phenolphthalein, or C20H14O4. It is an organic compound used as a laboratory reagent and pH indicator. It turns a pink to deep-red color above pH 9.  

What did you expect? A philter, perhaps?

kuroo regularly uses chemistry (or otherwise nerdy) pickup lines. most of the time it's an unprompted late night text, or randomly slipped into a lull in your conversation. no matter how many times he does it, it always manages to catch you off guard, and you're beginning to wonder if he'll ever run out. he won't.

these are some of his best ones: - i really hope uranium iodide is a compound because i think u and i belong together - are you a higgs boson particle? because without you, my universe wouldn't matter - are you c12h22o11? because you seem pretty sweet to me - i think you cut my phrenic nerve because you took my breath away - are you the base to my phenolphthalein? because whenever we touch i turn bright pink - i wish your name was avogadro because then i'd already know your number - are you the square root of -100? Because you’re a solid 10 but too good to be real!

this sort of nerd behavior is a green flag and i refuse to believe otherwise
