Colour is not a physical property of an object - it is a sensation, just like smell or taste. Colour is generated only when light of a particular wavelength falls onto the retina of the eye and specialized sensory cells generate a nerve impulse, which is routed to the brain where it is perceived as being colour.
Color is perception, and this picture drives that home. It makes us consider something altogether nonintuitive: that there's no such thing as white or gold or blue or black. “A color only exists in your head,” Lotto said. “There's such a thing as light.
Yet, here's the peculiar thing: as a physical object or property, most scientists agree that colour doesn't exist. When we talk about a colour, we're actually talking about the light of a specific wavelength; it's the combined effort of our eyes and brains that interprets this light as colour.
Colour is an illusion, not part of the real world
“Every colour that people see is actually inside their head … and the stimulus of colour, of course, is light.” As light pours down on us from the sun, or from a lightbulb in our home, objects and surfaces absorb some wavelengths of light and reflect others.
That's because it's impossible for the human brain to comprehend a colour not already present in our visible spectrum. (Bear with me!) As humans, we perceive the 3 primary colours (red, green, blue) which appear naturally in the environment. In our eyes, we have cone receptors.
If colours were simply a naming scheme for wavelengths then pink is not one, because it is made up of more than one wavelength (it's actually a mix of red and purple light). If you took a laser and tuned it across the visible wavelengths, from infrared through to ultraviolet, you would not pass pink on the way.
Warm colors – such as red, yellow and orange – can spark a variety of emotions ranging from comfort and warmth to hostility and anger. Cool colors – such as green, blue and purple – often spark feelings of calmness as well as sadness.
Point is, light comes in a lot of different wavelengths, but which wavelengths correspond to which color, or which can even be seen, depends entirely on the eyes of the creature doing the looking, and not really on any property of the light itself. There isn't any objective “real” color in the world.
Colour is not a halluncination.
By definition, a theory is not a fact. Yet, we often teach color theory as if it were irrefutable: Red, yellow, and blue are the primary colors that make up all other colors. Two primary colors make a secondary color.
So why is that? Part of the reason is that there isn't really a true blue colour or pigment in nature and both plants and animals have to perform tricks of the light to appear blue. For plants, blue is achieved by mixing naturally occurring pigments, very much as an artist would mix colours.
Can we be sure that people see the same colour when they look at something? Not at all - while the cones in our eyes suggest we're seeing something similar it's likely that we all see just a tiny bit differently. * Message us on Facebook.
Some consider white to be a color, because white light comprises all hues on the visible light spectrum. And many do consider black to be a color, because you combine other pigments to create it on paper. But in a technical sense, black and white are not colors, they're shades. They augment colors.
It has been determined by people who determine such things that there are somewhere around 18 decillion varieties of colors available for your viewing enjoyment. That's an 18 followed by 33 zeros.
The colors we use to describe emotions may be more useful than you think, according to new research. The study found that people with or anxiety were more likely to associate their mood with the color gray, while preferred yellow.
Color and depression: What's the link? When it comes to depression colors, gray and blue tend to be high on the list of those associated with low mood. In a 2010 study using the Manchester Color Wheel, experts found gray was the color people pointed to when asked to reflect feelings of depression.
Color Therapy
Research has shown that the “mood-altering effect” of color may only be temporary in many cases. A blue room may initially cause feelings of calm, but the effect dissipates after a short period. Studies have also shown that color can influence your performance.
Because the colors of light travel at different speeds, they get bent by different amounts and come out all spread out instead of mixed up. Violet travels the slowest so it is on the bottom and red travels the fastest so is on the top.
Because they're not treated the same as girls who wear blue. When it comes to gender, not all colors are created equal. As we all know, pink is the chosen color for girls and blue for boys. They're colors set in stone by decades of cultural stereotyping and gender-based, pink-blue marketing.
In old catalogs and books, pink was the color for little boys, said Leatrice Eiseman, a color expert and executive director of the Pantone Color Institute. “It was related to the mother color of red, which was ardent and passionate and more active, more aggressive.
Red-green and yellow-blue are the so-called "forbidden colors." Composed of pairs of hues whose light frequencies automatically cancel each other out in the human eye, they're supposed to be impossible to see simultaneously.
Blue is one of the rarest of colors in nature. Even the few animals and plants that appear blue don't actually contain the color.
Yes, you can imagine new "colors", and there are physically meaningful complex colors that humans don't really see.
