all light is the same. what makes it different is the frequency at which it oscillates. we can only see a tiny portion of the light spectrum. we have things called cones and rods in our eyes that react to certain frequencies of light, and send signals to our brain that correspond to their level of reaction. some people(like my brother) dont have certain cones or certain rods. so, those rods/cones are not there to 'accept' their certain light frequency, and therefore the signal for that color does not get sent. this is what color blindness is.

http://hyperphysics.phy-astr.gsu.edu/hbase/vision/rodcone.html
Current understanding is that the 6 to 7 million cones can be divided into "red" cones (64%), "green" cones (32%), and "blue" cones (2%) based on measured response curves. They provide the eye's color sensitivity. The green and red cones are concentrated in the fovea centralis . The "blue" cones have the highest sensitivity and are mostly found outside the fovea, leading to some distinctions in the eye's blue perception.

The cones are less sensitive to light than the rods, as shown a typical day-night comparison. The daylight vision (cone vision) adapts much more rapidly to changing light levels, adjusting to a change like coming indoors out of sunlight in a few seconds. Like all neurons, the cones fire to produce an electrical impulse on the nerve fiber and then must reset to fire again. The light adaption is thought to occur by adjusting this reset time.

The cones are responsible for all high resolution vision. The eye moves continually to keep the light from the object of interest falling on the fovea centralis where the bulk of the cones reside.

i suppose it is possible that each of our brains interprets the signals differently. we are both looking at a red spectrum light bulb, and our eyes react the same way by sending the signals to our brains. but maybe my brain interprets that red color differently than your brain. we will both know it is red because that is what our brain is perceiving, but in reality, the color itself that we see may be different.

color blind is indeed a different perception of reality. no different than if you wore a blindfold. but different is not better (walking is different than driving a car). the inability to distinguish one color from another is different, but not better by any measure, and can be an actual hazard.
color blind = handicapped.

yes it is. for instance, before my brother got a digital ph meter, he used those drops. either me or his mom(half brother) would have to check the colors on it for him

exactly my point!!

thanks...

can anyone think of a way to test this? how could we find out if we all really see the same colors in our brains? we know we are viewing the same spectrum, but do we perceive each uniquely? i think most of the descriptors we use for colors are just examples of other things with the same color. like blood red for example. so descriptions may not be able to test this

There is no molecular difirence between things of difirent colour.
Colour does not exist (actualy nothing physicaly exists, in the way that it is easiest to assume it does)
Everything that we percieve, touch, hear, smell, are just electrical signals in our brains. You have never even seen the sun, you have only seen the image of the sun in your brain.
Which is influenced by a host of factors.

I've always thought it would be fucked up to teach your child that red is blue... and blue is red...

like always refrence them as such, and when they get out into society it would completely blow their fucking mind..


But I'm not an asshole, and I don't have such time...


but @ op I'm glad i'm not the only one who has thought about this :lol: :lol:

I think the only possible way would be a huge neurological study to see how the brain reacts to viewing certian colors, and then reference the reaction with other peoples reaction. But even then i'm sure we would all have different signal and different interpretations.
