Can colorblind people see rainbows and if they can what do they see?

Answer 1

Colorblindness does not mean that you necessarily see in black and white . . . for most people it means you cannot distinguish certain colors that most people perceive. Red-Green is one common form of colorblindness, and they see blue just fine!

Our eye contains three kinds of light-sensitive cells, each sensing a different band of colors--one band centered in the red, one in the green and one in the blue. Any color which we see--including brown, olive-green and others absent in the rainbow--is an impression our brain conveys as it combines signals from these 3 color bands. Color-blind persons lack some types of eye cells, and their world lacks certain colors, or even (for those having only one kind of cell) any color at all. Color blindness is much more prevalent in men; in women, on the other hand, a rare mutation exists whose eyes have four different kinds of receptor cells. The rest of us can only guess what colors those ladies must be able to see!

There you have it,
have fun!

Answer 2

I'm red green colorblind and I can only see 2 to 4 colors. Those just so happen to be a little bit of red, green, and some yellow. I know that is odd because it's red and green that I am blind to.
I believe that is just proof that people who are red green color blind can see red and green at times and that it's more that the colors are impaired all around because I see red and green different from a normal person.

Just because your color blind, it doesnt mean you cant see anything. There are all kinds of colorblind ness.... some times its only a few colors that "they" cant see. For instance, I had a teacher that was red green color blind... well this posed a problem with driving because there are red, yellow and green lights. He knew that the red was the top light and the green was the bottom. To him, the lights were grey.. but he knows what they meant. When your color blind, you can see the object in the black grey white scheme..... or shadows i guess you could say.

yeah, rainbows are a lot less glorious to us. the rainbow spans the same light spectrum as you, but it blends together and i d say i see like three colors and they blur together. i have red/green deficiency.

i remember in grade school asking my teacher why paintings/colorings of rainbows never look like they do in real life. the teacher was as perplexed as i was. it wasn t until much later in life during an eye exam when my pediatrician asked me to cover one eye and read the line of letters above the green bar on the eye chart. i read the line, and she said, "Wow, OK - that was great but that s the line of letters above the red bar." I gathered that i had been (and continue to) make an educated guess my entire life. the line of letters i read off to her were lower than the line of letters that i was supposed to read, so i just guessed that that was what she wanted me to read. that is also when i found out that i have better than perfect vision. i have 20/10.5 vision.

nowadays it is pretty easy for me to guess colors, but in no way is it anything but a guess. smaller amounts of color, and colors that are isolated are the hardest. for example, navy blue and purple look so much alike that i went through my younger years thinking that purple was just a different shade of blue. so when i try to figure out if something is navy blue or purple, it is only really hard if i don t have the other color to compare it to. this is also true for light green and yellow, sometimes red and brown, brown/green, etc. etc. etc.

same with small amounts of color, if someone 15 feet away from me holds up a small navy blue button i wouldn t know if it was purple or dark blue without getting a close look, if they held up a big paper plate i could probably guess based on experience. if they held up a blue and a purple button, i could guess pretty easily.

think of it this way...for sake of argument, let s say that there are 1 million different shades in the entire color spectrum. let s also say that someone has been able to display the entire light color spectrum (detectable by the human eye) for you, going from white to black and going all the way across the page of 11.5 x 8 inch piece of paper. when i look at this same piece of paper, i might see 900,000 shades in between white and black where you see a million.

keep in mind i am not a scientist, nor do i think there is a finite amount of shades in the color spectrum (i have no idea, i am a layman).

but anyway, this has always been my go to example for when people ask me what it s like to be colorblind. to be honest, i have no idea - and i could ask them a similar question! what s it like NOT to be colorblind?

Answer 5

Turn your digital camera setting to take a black and white picture of a rainbow. The resulting photo is what the rainbow would look like to one who is colorblind.

Answer 6

Yes, they can see the rainbow and they see it as shades of grey instead of the different colors.

Answer 7

It depends on how many colours they are blind to? There are 7 colours which a normal person can see. I f he is just colour blind to one colour- then he will see all other 6 colours and 1 black and white colour
