There are an infinite number of fundamental colors, if by "fundamental" you mean "spectral". Spectral colors are also known loosely as rainbow colors. A spectral color is composed of a single fundamental color on the visible part of the electromagnetic spectrum, as opposed to a mixture of colors.
Yes, the number of colors is definitely finite. Color is strictly a perception; it has no physical existence. And while the spectrum may be continuous, that by no means implies an infinite number of colors.
It all sort of depends on what exactly you mean by “infinite.” 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.
If we use RGB, the range of colors is 0-255. Meaning there are 256 possible values for each Red, Green and Blue. 256^3 is 16,777,216. Therefore, the answer to your question is 16,777,216.
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.
The maximum number of colors that can be displayed at any one time is 256 or 28.
Fun Fact Friday: The Human Eye Can See 10 Million Colors.
What happens when you mix different colors of light? Unlike mixing paint, which will give you a darker color, when you mix all the colors of light, you get white light!
Magenta doesn't exist because it has no wavelength; there's no place for it on the spectrum. The only reason we see it is because our brain doesn't like having green (magenta's complement) between purple and red, so it substitutes a new thing.
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.
True color (24-bit)
224 gives 16,777,216 color variations. The human eye can discriminate up to ten million colors, and since the gamut of a display is smaller than the range of human vision, this means this should cover that range with more detail than can be perceived.
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.
The team determined that the average color of the universe is a beige shade not too far off from white.
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.
First, no two colors can be mixed to create a primary color. In other words, primary colors can only be created through the use of natural pigments. Secondly, all other colors found on the color wheel can be created by mixing primary colors together. The secondary colors are orange, green, and purple.
But when it comes to nature, blue is very rare. Less than 1 in 10 plants have blue flowers and far fewer animals are blue. 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.
The color of the sun is white. The sun emits all colors of the rainbow more or less evenly and in physics, we call this combination "white". That is why we can see so many different colors in the natural world under the illumination of sunlight.
When white light is passed through a prism, it splits into seven different colours namely, red, orange, yellow, green, blue, indigo and violet. If we do the reverse, that is mix the beams of light of all colour, white light is obtained.
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.
The average number of colours we can distinguish is around a million.
Most humans can see about 1 million colors. Some people can see around 100 million. This 4-minute video by DNews is an interesting look at this condition, which is known as tetrachromacy. The average human eye contains 3 types of cones that are sensitive to red, green, and blue wavelengths of light.
Although there are standard colors for every anniversary year up to the 25th, and colors for every five years to the 75th anniversary, there are few conventions for reaching the 100-year milestone. Although purple tends to be the most commonly used color, the choice is up to you.
Like 24-bit color, 32-bit color supports 16,777,215 colors but has an alpha channel it can create more convincing gradients, shadows, and transparencies. With the alpha channel 32-bit color supports 4,294,967,296 color combinations.
The human eye is estimated to see a pretty wide range of hues – between one and ten million. A computer monitor? It could be 65,000 or 16.8 million colors.
All colors on a computer are made up by combining the light from three colors (red, blue, and green). Black is [0,0,0], and White is [255, 255, 255]; Gray is any [x,x,x] where all the numbers are the same. The max value of each of the colors is 255.
