What could be really exciting, is that we could develop a way to see other colors. Butterflies see many more colors than Humans and there are rare cases of humans with an extra cone receptor.
- VBprogrammer 8y agoThat might be really fun for you but for me I'd really be much more excited about being able to see colours well enough to achieve my life long aim of being a pilot. As well as avoiding 1000 tiny annoyances that come with not being colour normalative. Maybe I'm just being sensitive but it's almost like someone was discussing a way to regrow a missing limb and you've come along to tell us you've always fancied a third hand.

Are you sure that colour blindness would still present an issue? I've heard that in recent years the requirements had been relaxed around this.
- VBprogrammer 8y agoI'm sure.
- dalbasal 8y agoIn fairness, "always fancied a third hand" is a comment you'll find on prosthetic limb HN threads, including today. I don't think one negates the other.
- antt 8y agoThis makes about as much sense as complaining about cosmetic dentistry because you've lost a tooth.
- rincebrain 8y agoI didn't think we had any confirmed examples of human tetrachromats?
- Tor3 8y agoThis Wikipedia article has something about it: https://en.wikipedia.org/wiki/Tetrachromacy https://en.wikipedia.org/wiki/Tetrachromacy Women can, in principle, develop something approaching tetrachromacy because the genes for two cone cell pigments are located on the X chromosone, and women have two of those. If the two copies of the genes are both active, and behave a bit differently, then it's conceivable that you could get some cones that react to a slightly different frequency. The article says some men could also develop this - not sure how, though. On the other hand the article also mentions just a single really verified case of a woman who had true tetrachromacy. After 20 years of study..

- rincebrain 8y agoI'd imagine any combination of {duplication and mutation on the blue cone gene which isn't on X, mosaicism or Klinefelter syndrome, transposition from X or replication on X with mutation} would work for you. Maybe not Klinefelter because of X-inactivation, I don't know how those two things interact offhand. I _think_ the key point is, as you said, that the different gene copies need to have different response ranges, or you end up functionally trichromatic even though the pigments are from different places.
