what if the world was everything black and white and grey? no any colours?
Well put! I just examined a white area of my colored monitor with a magnifier and I saw red, green and blue segments; (none of these where white).Pengwuino said:Well since white is a combonation of all the visible spectrum... I'm not sure how that's possible.
Pengwuino said:my magnifier isn't good enough to pick them up :P
White is a combination of all colors, and black means no color.Pengwuino said:Well since white is a combonation of all the visible spectrum... I'm not sure how that's possible.

Funny, that's the first thing I thought of when I saw this thread. Here's a synopsis I found for those who haven't read it:zoobyshoe said:Oliver Sacks treated a guy who lost all color vision after a freak bump on the head in just the right spot in a car accident.
Everything was shades of grey for him which made many things repulsive, especially food.
I wish I still had the book. I remember being fascinated that it wasn't the cone cells in his eyes that were damaged, but part of the brain involved in processing the color information. He suffered a whack on the back of the noggin, I guess? I can't remember the details. I found the following information about the disorder:Sacks begins with a portrait of Mr. I., a visual artist who, due to brain damage, can no longer perceive color. Mr. I.'s extreme case of cerebral achromatopsia, or color-blindness, is a result of seeing with wavelength-sensitive cells only, and not the brain's more sophisticated mechanism for perceiving color. As Sacks describes, the artist sees a “prechromatic” world that fluctuates as light changes.
In each of Sacks' portraits, an individual's loss becomes a story of transformation. After one year without color perception, Mr. I. moves into a productive period of black-and-white paintings. Those who do not know about his loss see this phase as a reflection of creative renewal and artistic development. When presented with the possibility of having at least some of his color vision restored, Mr. I. rejects the idea. The world he perceives is too solidly re-constructed—in Sacks words, too "coherent and complete"—to alter. Color, on the other hand, no longer holds its previous associations and, in this way, no longer makes sense to him. The idea of substituting his "prechromatic world" with the lost world of color becomes just as unimaginable for Mr. I. as a colorless world might seem to those who have never experienced it.
I have no idea what a "bilateral ischemic infarction" is. Or "Bilateral upper homonymous quadrantanopsias" either.To the patient, the sudden onset of cerebral achromatopsia is like switching to black and white on a color TV. As a rule, the defect arises due to bilateral ischemic infarction in the inferior occipitotemporal region. Bilateral upper homonymous quadrantanopsias usually leave the macula more or less unimpaired, so that visual acuity is largely preserved. Prosopagnosia and loss of topographic memory are often associated with central achromatopsia. Investigations of color vision must include color-naming procedures and largefield tests in addition to the conventional methods. Color-naming tasks are indispensable in differentiating cerebral achromatopsia from the aphasic and disconnective types of color anomia.
It cololerd blind.Sometimes people who color blind can't see any color's but they can tell the differnce it's kind of like when your watching TV from the 60's you when the just had black tv back then,you couldn't see any color's but you could kind of tell which were whichmoose said:What if your brain could only "show" you black and white? Some people have messed up cones or whatever and have that problem too...
Good quotes you found there.Math Is Hard said:I have no idea what a "bilateral ischemic infarction" is. Or "Bilateral upper homonymous quadrantanopsias" either.

I think that it would be like dimming of the light. A white surface is reflecting all the visible colours of light in the spectrum. A black surface is absorbing all the visible colours of light in the spectrum. By combining the effect of the white with the effect of the black you more or less "dim" the reflected light. There is no grey in the spectrum of colours of light.debeng said:if white means all coulour and black means none? what would grey mean?
A world without color is a hypothetical scenario in which all colors, including black and white, do not exist. This means that everything would appear in shades of gray, and there would be no differentiation between colors.
A world without color would have a significant impact on our daily lives. It would affect how we perceive the world around us, from the clothes we wear to the food we eat. It would also impact our emotions and mood, as color plays a crucial role in evoking certain feelings and emotions.
While it is not possible for a world completely devoid of color to exist, there are some conditions that can create a perception of a world without color, such as certain types of color blindness or living in a monochromatic environment. However, a world without color as portrayed in fiction is not scientifically possible.
Nature and animals would also be greatly affected by a world without color. Many animals use color for camouflage, communication, and mate selection. Without color, these animals would have to adapt to new ways of survival. Plants would also be affected, as they use color to attract pollinators and photosynthesize.
The psychological and emotional impact of living in a world without color would be significant. Colors have a strong influence on our emotions and can evoke different feelings. Without color, our world would appear dull and monotonous, which could lead to feelings of sadness, depression, and even anxiety. It would also affect our ability to express ourselves creatively through art and design.
