>>44791516Hate to dash your dreams, but while we have no indication as to what color their circulatory fluids might be, the URS are still clearly primarily humans at a biological level, which means they have the same iron-rich red blood and hemoglobin-containing muscle cells, which would realistically have no reason to function differently if Ultra Megalopolis is perfectly sustainable for an outside human like the player character, even after centuries or millennia of separation. Their only significant divergence from regular people appears to be their primary melanin levels, which explains the nonexistent pigmentation and faded eye colors. Ergo, they're more than likely red on the inside, if not at the very least an imperceptibly darker shade. You have to keep in mind, these guys are arguably about as far apart from you and me as a white European and an African native.
