Yes Sir! The NTSB requires that reflective vests are ORANGE for exactly this reason! Same with all construction signs. They used to be yellow and red years ago.
The only signs that haven't changed in the US to accommodate color blindness are Interstate and Stop/Wrong Way signs. Interstate signs are no problem because they are green with white letters, but Stop signs are different. They are all red with white letters, and while the red washes out silver for me, the white letters are still glaring, especially at night! But really, the color of your scooter doesn't matter... if you buy a red one, it looks just like a silver one to me -- a green one is a yellowish color, etc. It's not like they disappear! :-) -Rich

From 30+ years in the Medical field...I will say that yes about 10% of the population is Red/Green color blind. This rarely if EVER occurs in females. Now I will interject a bit of my Native American teachings that are Wildlife Biology supported. In nature you will notice most female animals are well camouflaged decorated in earth tones..this helps them blend in and guard their offspring....while the male of the species is very colorful. For example Pheasant,Ducks,Partridge,Hawks,Eagles,Song birds and the list goes on...with the exception of Deer,Bear,Felines and a few others whose offspring are born with an earth blending color for protection. In the case of Bears, Felines and several others..they need not be of an earth blending color for they are the very predators at the top of the food chain. The males of most species need not complete color vision as they themselves are the brightly colored ones...whose colors and mating ritual is what attracts the female for breeding purposes. While at a greater risk by being so colorful it does not upset the balance of nature as one male can mate with several females producing plenty of broods of offspring.(Gee sounds like something we see on the Maury Povich show huh?) Should his bright colors keep him from concealment and an easy target for predators...it does not matter for another male can replace him in the reproductive cycle. Oddly human males are not of bright colors...but then again we are also at the top of the predator/food chain. How does this apply to the OP and all other posts on it...not really sure. I am just a plethora of trivial crap as my gf tells me. But that is because I do my best to view things from another perspective..satisfy my curiosity and try my best to understand the nature of animals and humans. Hence my name..Yayiima benatigee...meaning in touch with nature or blends with nature. There will be no homework for tonight's biology lesson..however you will now be more aware of...the colors of human and animal nature.

As modern science is well aware of now, humans evolved from primates, including baboons who are very usefull for this discussion. In baboons red buttocks on a female indicates to a male that she is ready to breed. One theory suggests that the "arse end advertising" of the baboon reproductive cycle has been inherited by modern man, in that the shape of a woman's body (curve of the shoulders, cleavage, shape of the knee etc) is designed to replicate a nice bum. Moving on from that, you can see how any male baboon (looking for a red arse in a green jungle) with red/green colour blindness would have failed to mate, and thus any descendants in the evolutionary tree, would have excellent colour differentiating vision. I personally would suggest that red/green colour blindness is caused by a random configuration of genes, activated by the "Y" chromosome, hence only ever in males. But that is purely an (un)educated guess: I'm an engineer, not scientist! Lol If you've got anymore pearls of wisdom, keep them coming, that was very interesting! |

Anyway back to your OP. I would have to concur that the Y Chromosome is somehow instrumental in color vision just as it is other in other inherent traits in male vs female. The odd trait that we do share is that both men and women carry both Testosterone and Progesterone..each at a proper level to keep our male/female traits. Androgen while a type of testosterone is found in both but higher so in males. Studies I've read have shown that too much male hormone Androgen causes Acne and can be seen notably more in thin girls with a 12 yo boyish figure..for they suffer Acne worse than the average human. So again..back to your Op...bear with me..I get lost in thought at times. Attraction for human males and females also comes from the eyes in how they are used when engaging in conversation. Possibly why we all have different eye color as only one color may not attract everyone? Not sure. Medman the Moderator is a PA...he will come along soon I hope...and correct either of our discrepancies..explaining it backed by his in depth knowledge. |
