Color blindness, also know as color vision defects, is the difficulty or inability to tell the difference between some shades of colors. Frustrations for those with color blindness include reading color-coded maps, buying clothing, and traffic lights.
Dogs are not color blind - they see color, but their chromatic
acuity is significantly less than humans'. This is for two reasons:
(1) dogs have far fewer cone cells in their retina (cone cells are
responsible for seeing color); and (2) dogs are dichromatic (they
see only two primary colors - blue and yellow) whereas humans are
trichromatic, meaning we see three primary colors - red, blue, and
Humans have 7 times higher proportion of cone cells than dogs,
Some animals are color blind... Just some can see some certain
colors, like a horse can see blue's and greens, deer can see
yellows and greens..etc...
Dogs most definitely are not color blind. There are some
differences in their vison from that of humans, but -- contrary to
popular myth, their eyes contain both rods (cells that detect light
and movement but not color) and cones (which detect color and need
more light than rods do in order to activate).
Rods are groups...
Yes, of course glitter is a color. It's not only a color, but also
a way of life. Glitter is a life changing substance that has its
own personality. If you believe in the magic that is glitter, your
life will be glitterfied. Some people are dropped as a kid that's
why they think glitter is not a color. I however, was dropped in
glitter, so I know the truth.
Beat it, meaning cheat on it? Sure. Plenty of ways. You could
study the test ahead of time so you know by the patterns what
number is there; you could have a non-colorblind friend tell you
the friendus; you could bribe the doctor... so many ways.
My question though is why in the world would you want to? The
test isn't for a grade... it is to determine whether you are
colorblind, and that is something that it is helpful to...
You can't describe it. The color pink is strictly visual - it is
a light of varying wavelengths and frequencies. Just like you
couldn't answer what pink sounds like; the color pink will
always remain foreign to a blind person.
That is a beautiful question you have. Pink is the soft pillow
you felt as a baby or the soothing voice of your mother. You could
also describe pink using the sense of taste, such as bubble gum
flavored ice cream.
Blue rather than green is the colour associated with St. Patrick
and some flags were "St. Patrick Blue" in colour.
Also the Irish flag that still appears on the English Royal
Family's coat of arms is navy blue with a gold harp.
It can be seen on photos of Princess Diana's casket if you're
curious as to what it looks like.
In response to Claire that's a Leinster flag not an Irish
Note - That is actually the Irish crest on Diana's
I was told by a pool supply store in Cleveland, Ohio, that they
have heard of more instances of the black covers falling apart than
the others. The guy in the store suggested it is because the black
absorbs more of the sun's heat, causing the more rapid breakdown in
the material. He had heard nothing about the clear covers, but
speculated that it would hold up better than the black. Swimming
pool covers help retain pool heat by reducing evaporation....
Here are opinions and friendus from Wikifriendus Contributors:
Here's a toughie...Firstly, i think it depends on the person.
If a person is old enough, it may occur as black and white.
Otherwise though, I'm pretty sure it's mostly color dreams.
People dream in color, even when they think that they dream in
black and white... if you ask them what color something was, they
No, I don't dream in color and I am normal - as normal as

Speaking somewhat physiologically and psychologically, yellow is
apparently the most significant colour that makes people want to
eat (so a definite bad idea for the kitchen), however probably
because we often associate red with feelings and emotions tied in
with love, passion etc. Therefore people see it, it's a warm
colour, we feel that instant comfort and security etc. Hope that
starts you off.

My guess is the video card is going bad. Try replacing that. If
you have a spare monitor you may want to try viewing your desktop
on a different monitor before going out and buying anything.
First thing I would check is the cable between your monitor and
computer. Swap it for another cable if you can detach it from the
back of the monitor. If not, leave it be. The inside of a CRT
monitor is a dangerous place. You...
Sharks can only see in shades of grey.
Findings from a study by Australian scientists, released in
September 2012, show that sharks' eyes have just one type of cone
opsin - or light-sensitive proteins found in the photoreceptor
cells of the retina - instead of thevtwo or more that are needed to
see colour. Cone opsins are used to help animals see in bright
light, and to differentiate between colours.
Monochromatic colors are all the tints, tones, and shades of a
particular color or hue. You typically see this on a paint sample
card, for example, with lighter and darker shades of the same base
If the person has been blind all of their life, explaining color
to them would be impossible. How can anyone have a conception of
what color even means, if they never had the experience of seeing
anything except darkness?
A person who has never ever been sighted also has no concept of
darkness, since darkness is a visual experience. This can be a
difficult concept for a sighted person to get....
