Color Blindness

This is not exactly true. Most colorblind people can still see color and do not see entirely in black and white. Normally they just have trouble distinguishing between similar colors, such as blue and green.

Yes, hamsters are color blind and see black in white. Make sure you don't put them in direct sunlight because then they are practically blind and can't see that good.

Yes, Itachi went blind because he used his Mangekyo Sharingan multiple times with the Mangekyo Sharingan's use, it starts to corrode your vision. The only way to restore your vision and not have any side effects of using the Mangekyo Sharingan is to plant another person's Mangekyo Sharingan into yours.

In my opinion, black is the easiest colour to describe to a blind person. Ask the person what they see? When they answer nothing, that is the colour of black. Dark, unseeable. Or at least that is how I would describe it.

If it was someone who had previously had sight, easy.

If it was someone born blind, you could word it like this, "Imagine the thing that you are feeling in front of you absorbs certain kinds of light, - you've probably noticed light if you were in a bright place and the darkness you see lessens - if it absorbs all kinds of light, it appears blank, if it doesnt, it appears as darkness, of which you probably see. depending on the kinds of light it absorbs, it can become more or less blank without being only blank and black. It could seem like it is getting bigger, and having less detail, this is when it gets fuzzy." Like it?

you can't see colors
It means that they can't see certain colors, usually red, yellow, and/or orange. It can also mean that they see colors differently then we do, for example your orange might be their red.

you can't predict that. it depends on what sex the offspring is. if it is a female, she could be color blind because her father is, but a male could be color blind either way. because color blindness is carried on the Y chromosome and not the X chromosome.

It may be impossible to teach them what the experience of color is like. You can however teach them about the science behind color. It is different wavelengths of electromagnetic radiation. You can also explain it by analogy. The blind can recognize textures. Color is sort of the same in that is a property of surfaces that we can experience.

The Ishihara test is comprised of eight plates that are similar to the American Optical Pseudoisochromatic test plates. The individual being tested looks for numbers among the various colored dots on each test plate.

Feral pigs (like all pigs) have dichromatic vision. Their eyes have cones sensitive to wavelengths in the blue-green portion of the spectrum, but it is unclear whether this translates to color perception in the way we humans understand it. They do not seem to perceive contrast the same way that we do (although they DO perceive it) and only have depth perception within 15 degrees of either side of the snout. They have very sensitive peripheral vision that is particularly good at detecting lateral motion.

From a practical standpoint, this means that you are essentially invisible to a feral pig if you are wearing clothing of the same tonal value (regardless of color) as your surroundings and do not move laterally relative to the pig's head.

50/50 because the child gets 26 chromozones from each parent so the chances are 50/50.

-Peripheral areas of the retina contain very few, if any, retinal cones. Those areas contain only rods, which cannot distinguish color.

-Cones are necessary to see color, there are 3 types of cones (red, green, and blue), mostly concentrated in the center of the macula, which is known as the fovea.

You do not get color blindness, you are either born with it or not born with it. It is on the X chromosome. A male has one X chromosome. A woman has 2 X chromosomes. If one X chromosome does not have red-green capability and the man has that chromosome, then he is color blind. A woman can have one color blind chromosome and one non-color blind chromosome and she will not be color blind. The ability to see blue and yellow is on chromosome number 7. Everyone has two of those. A man can only have 3 color chromosomes. Women can have 4 color chromosomes. Since the chromosomes can be slightly different, women can frequently see far more color variations than men can see.

Color blindness is a problem with the retinal receptors in the back of the eye and LASIK in no way can help this problem.

The scientific name is "glaucoma". But there are different entities...

No, bulls cannot see red. Since bulls are cattle, they only have two receptors, not three like us humans have. These two receptors are blue and yellow. Humans have red, blue and yellow receptors, and thus are able to see in full spectrum. Cattle cannot. Yellow-green and bluish-purple hues are the main hues that cattle are most attuned to.

Thus, in the Spanish bull fighting ring, the Spanish Fighting Bull is only responding to the quick rapid movement of the cape, not the colour.

First reason is they could have been great decedents of the Tribe Norse. They could have had there vision of color sacrificed to Great Valhalla(psst...its were were the dead guys go) And wen the color is gone they donate it to little Chinese people so they don't put lead in our toys

Connotations of the colour black are mostly negative and associated with a dark skin color of people in america.

"Black is associated with power, elegance, formality, death, evil, and mystery. Black is a mysterious color associated with fear and the unknown (black holes). It usually has a negative connotation (blacklist, black humor, 'black death'). Black denotes strength and authority; it is considered to be a very formal, elegant, and prestigious color (black tie, black Mercedes). In heraldry, black is the symbol of grief."

In a sense you are correct. The sky is every color in the rainbow including green. The reason we see blue is because in the spectrum this is the last color that doesn't disperse throughout the atmosphere before it reaches our eyes.

No, most turtles have broader color vision than humans, including limited UV range.

Yes and no. some people are only color blind when certain colors meet for example: if you were black and yellow color blind a bee would only be one of the colors.

Yes, color blindness can skip generations.
