This is for actualmenacebuckybarnes, becase this shit is way too long for an ask.

Okay, so what we know the serum did:

1. Put on muscle and bone mass.
2. Increased his metabolism by 4, according to the Marvel Guide Book
3. Gave him increased…

Color-blindness isn’t caused by the lack of photoreceptors. It’s caused by those photoreceptors not being differentially expressed. In normal color vision, a cones sensitive to “red” wavelengths of light and cones sensitive to “green” wavelengths are never expressed in the same cells. So you, literally, have cells that only “see” red (let’s call these guys Cyclops cells) or only “see” green (Hulk cells). When red light hits your retina, the “red” photoreceptors cause the Cyclops cells to tell your visual cortex they’ve been beamed with photons. Likewise, green light evoked a similar response from the Hulk cells. This is the only time segregation based on color is ever a good thing, btw. In color-blindness (more accurately, “color confusion”) you get red photoreceptors and green photoreceptors expressed in both cell types. So Cyclops cells shout to the visual cortex when they see red or green light instead of only when they see red. And the Hulk cells smash when they see both colors as well. As a consequence, the brain can’t tell red light from green light. A similar process happens in the much less common yellow-blue color confusion. We are much more likely to suffer genetic diseases and disorders as a result of these epigenetic phenomena than we are from actual loss of genes.
