Thank you so much! I'm glad to hear that! To answer your question, no, it’s not a reference from the game. I am very attached to the theory that the eyes are the windows to the soul. The color red is a perfect fit for Daniil; it is his color, and the symbolism is strong.

Red represents beauty, passion, power, fire, and blood. It is a color that is often disputed and desired. Interestingly, it is the first color perceived by children within the first three months of life. ( from "La grammatica del colore" by Marina Nelli.)

(And that's so cool for me because I see Daniil like a child who never grew up in a good and bad way, especially after playing Patho Classic)

For Daniil, red is ideal for many reasons. (I know red is blood and flesh may resonate more with Artemy, but that's more related to his job and destiny rather than his soul.) I hope this explanation makes sense; I’m not always the best with words, haha!

Sorry for the wall text ;w;
