The post discusses a groundbreaking experiment where researchers at the University of Washington aimed to create new colors perceived by stimulating individual photoreceptors at a population scale. The study involved five subjects, including coauthors and lab members, raising ethical questions about self-experimentation. Furthermore, some commenters compared the technology to concepts in science fiction, like Neal Stephenson's *Snow Crash*, highlighting the blend of real scientific exploration with fantastical ideas about virtual and augmented realities. This suggests that the research may lead to both practical applications in vision science and speculative futuristic developments.
